Analysis read time and "too many catagories"
by epidata-list＠lists.umanitoba.ca 26 Oct '05

26 Oct '05

greetings. i have atached a .rec file with 165,905 records, each 44 bytes. (1) it takes EpiAnalysis 10 seconds to open compared to instant availability in Epi6. why so slow? (2) using EpiAnalysis FREQ DATE resulted in error... "Too Many Catagories", no output. why??? (3) using Epi6 time for FREQ DATE was 1.9 seconds. slowness we can perhaps tolerate but no output on FREQ may be an issue. Or, it could be ther user. thank you and stay safe, kelly -----Original Message----- From: epidata-list-bounces(a)lists.umanitoba.ca on behalf of epidata-list-request(a)lists.umanitoba.ca Sent: Tue 10/25/2005 1:01 PM To: epidata-list(a)lists.umanitoba.ca Cc: Subject: EpiData-list Digest, Vol 24, Issue 13 Send EpiData-list mailing list submissions to epidata-list(a)lists.umanitoba.ca To subscribe or unsubscribe via the World Wide Web, visit http://lists.umanitoba.ca/mailman/listinfo/epidata-list or, via email, send a message with subject or body 'help' to epidata-list-request(a)lists.umanitoba.ca You can reach the person managing the list at epidata-list-owner(a)lists.umanitoba.ca When replying, please edit your Subject line so it is more specific than "Re: Contents of EpiData-list digest..."

Using Epidata for a central server
by epidata-list＠lists.umanitoba.ca 26 Oct '05

26 Oct '05

Hello 1.About having a central server, please refer to the website and read the limitation of Epidata. 2.Well you can use the qes for data management or also use the option of preparing one data screen(rec file)and use the option of copy structure which is located at the tools menu.The advantage is that; 1. It is fast 2. There is no need to prepare another check. With these option, data entry staff can entry data for you and you have to merge them to have a collective data either at epidata or using spss. Using text fields.It is possible to enter open-ended questions and narrative with Epidata but it limitatiton is that it takes up to 80 characters whilst that of spss DE takes about 256 characters SEDZRO KOJO MENSAH P.O.Box AS 387 Ashaiman -Tema Ghana House : +233-22-300789 MOBILE : +233-244-458788 Homepage http://rastafarionline.com/rasbesa Open WebMail Project (http://openwebmail.org) ---------- Original Message ----------- From: epidata-list-request(a)lists.umanitoba.ca To: epidata-list(a)lists.umanitoba.ca Sent: Tue, 25 Oct 2005 12:01:20 -0500 (CDT) Subject: EpiData-list Digest, Vol 24, Issue 13 > Send EpiData-list mailing list submissions to > epidata-list(a)lists.umanitoba.ca > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.umanitoba.ca/mailman/listinfo/epidata-list > or, via email, send a message with subject or body 'help' to > epidata-list-request(a)lists.umanitoba.ca > > You can reach the person managing the list at > epidata-list-owner(a)lists.umanitoba.ca > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of EpiData-list digest..." ------- End of Original Message -------

External reference for data entry: length limitation
by epidata-list＠lists.umanitoba.ca 25 Oct '05

25 Oct '05

Dear friends. Using COMMENT LEGAL function in order to select strings and get their respective codes from a separate REC file, I wanted to get CID10 codes and their respective Descriptions during data entry. In my parent CHK file you can see: DISEASE COMMENT LEGAL CID10.REC SHOW TYPE COMMENT CIDCODE END CIDCODE NOENTER END In my reference CHK file you'd read: DISEASE KEY 1 END CID10 KEY UNIQUE 2 END It's working fine, except that, in the pop-up window of reference the description of DISEASE is shown length limited to 30 characters, despite of my reference REC file showing 70. Any clue? Thanks in advance.

Re: Multiple locations input
by epidata-list＠lists.umanitoba.ca 25 Oct '05

25 Oct '05

Well, Megan. As I know, simultaneous entries are not possible. I have been using EpiData in clinical research and constantly dealing with multiple users input. Right now I am creating a set of files to be used for a multicenter study about Neonatal Care Units (up to 50). What I do is to distribute sets of REC/CHK files (named specifically after each center) and recover the filled REC files through the use of a Web based free, but access-limited Group (like Yahoo Groups), what turns to be a additional backup system for my precious files. Having different files make it possible to first check the adequacy of each file before combining them. Combine files is quite fast and easy. Hope it helps.

Multiple users - question by Megan Reif
by epidata-list＠lists.umanitoba.ca 25 Oct '05

25 Oct '05

Dear Megan: I can tell you a bit about our experience with multiple users in different countries we have had. We use one original set: original.qes original.rec original.chk Once this is definitively agreed upon, we use Copy structure (including the check file) to get: a.rec a.chk b.rec b.chk .. as many as we need and give one pair to each user (actually in duplicate for double entry). They enter the data at their leisure and then email the validated *.rec files. Because these files are so small, this can be done from even the slowest email connection (which matters to us as we work in some of the poorest countries). In EpiData Analysis, we simply do: close erase "abcd.rec" read "a.rec" append "b.rec" append "c.rec" append "d.rec" savedata "abcd.rec" close read "abcd.rec" People in the periphery simply continue to enter data into a.rec or b.rec and send so and so often the updated file, and the coordinator runs the append.pgm again. We did this with 30 locations in Zimbabwe collaborating with 31 locations in Mongolia, with a similar set-up for Moldowa collaborating with Uganda, and we never had a need for a central server. Email did just fine. A file with 58,000 records and and 9 fields took just 2 MB. I hope this helps a bit with that part of your question. Regards, Hans Rieder

Remote Entry, Multiple Users, Long Text Fields
by epidata-list＠lists.umanitoba.ca 24 Oct '05

24 Oct '05

Hello, I am a political scientists but used to work with public health people at The Carter Center. I am comparing EpiData, SPSS Data Entry Builder, and File Maker Pro as options for entering media incident reports of election violence. I am interested in "epidemiology of political violence" and eventually plan to map incidents. I am leaning toward Epi because it is freeware and many other great qualities, but a couple of questions remain: (1) I would like to have people entering data at the same time from multiple locations. Is it possible to have a remote and immediate data deposit on a central server via the web using EpiData? If not, how have people handled data management when field staff enter data? Do they just use the same .qes and then send the .rec files periodically, which are appended. Are there any problems with this method? I was thinking of setting up a web site where people could upload their files, then I would combine them. (2) I am a bit confused about text fields. Is it possible to enter open-ended questions and narratives (paragraph length)? This is what is attractive to me about SPSS DEB. They have remote entry as well as long text fields. If anyone has considered these issues I would welcome assistance. Best wishes, Megan Reif Megan E. Reif Department of Political Science University of Michigan 5700 Haven Hall 505 S.

How to go for new record if you have two parts in EpiData?
by epidata-list＠lists.umanitoba.ca 21 Oct '05

21 Oct '05

Hello! I have database made of two parts. When we finish data entry in "part 2", instead of moving to new record file, and we expect to see part 1, we get new record file in part 2. Example: when we enter questionnaire number 1-part 1. Then part 2 opens for the same questionnaire 1. At the end of part 2, instead of moving to questionnaire 2 to start doing data entry, it gives us new record file under part 2 for questionnaire 1. Any advice(s)? Thank you in advance!

Re: Double Entry Error and @ when exporting to SPSS
by epidata-list＠lists.umanitoba.ca 14 Oct '05

14 Oct '05

I have a problem with results of calculation during double entry. During > double entry, all calculations give same results as first entry except only > for few subjects. Mystery sometimes happen - I am not sure what the problem is here. But we are just now working on different aspects of double entry verification. With the next build of EpiData Entry these errors should be fixed. For the finding of errors it would be very good if users could supply us with the rec+chk files giving problems. If someone as indicated on the list recently have examples creating problems please provide them for us for testing. The known issues to settle are: 1. Sometimes the double entry verification does not move on to the next record (problem with range definition in last field) 2. The calculation error indicated today. Send the files as zipped files (e.g. with few records, say 2-5) to info @ epidata.dk with a clear subject indicating that this is not spam, e.g EpiData test case for finding double entry problem. 2. Exporting to SPSS from old to new version of EpiData. The EpiData file format has not changed apart from the addition of encrypted fields and <yyyy/mm/dd> fields What most likely cause your problems is that the setting of "variable name" as first word or automatic was different on the two computers. Also for export to SPSS you do not need the QES file, but the chk file (definition of value labels and missing data) + the rec file (definition of fields, variable labels and all of the data). regards Jens Lauritsen EpiData Association

problems with calculations during double entry
by epidata-list＠lists.umanitoba.ca 14 Oct '05

14 Oct '05

Hi, I have a problem with results of calculation during double entry. During double entry, all calculations give same results as first entry except only for few subjects. I checked my formulae with other software and they look OK. This bug is not systematic thats why I have difficulties finding errors. I dont understand why this bug appears only for few subjects. They have not the same characteristics. Who can tell me what king of error it could be, because I dont know anymore what to looking for? Below, calculations : pspef AFTER ENTRY IF (sex = 1) and (height < 162.6) THEN pspdpef=(height * 0.073) - 5.98 ENDIF IF (sex = 1) and (height > 162.5) THEN pspdpef=(height * 0.125) - 13.14 ENDIF IF (sex = 0) and (height < 152.6) THEN pspdpef=(height * 0.079) - 6.79 ENDIF IF (sex = 0) and (height > 152.5) THEN pspdpef=(height * 0.064) - 3.94 ENDIF IF (sex = 1) THEN pssdcpef=(pspef - pspdpef) / (pspdpef * 0.18) ENDIF IF (sex = 0) THEN pssdcpef=(pspef - pspdpef) / (pspdpef * 0.2) ENDIF psppef=(pspef/pspdpef)*100 END END pspdpef NOENTER END pssdcpef NOENTER END psppef NOENTER END Example : sex = 1 , height = 132.8, pspef = 4.90 First entry (good results) pspdpef = 3.71 pssdcpef = 1.78 psppef = 132.1 Double entry pspdpef = 3.71 pssdcpef = -1.15 psppef = 79.2 Thank you in advance for your help.

Using stattransfer to solve corrupted file
by epidata-list＠lists.umanitoba.ca 12 Oct '05

12 Oct '05

Another form of solving a corrupted file is to use statransfer(a statistical software that enhance file transfer from one format to other eg. from spss file to rec or any other file)with this software you transfer the file back to rec and it will solve your problem.

How to: Recapture a corrupted file
by epidata-list＠lists.umanitoba.ca 12 Oct '05

12 Oct '05

In some versions of some computers open files can get "messed" up if power is suddenly lost. Over the years we have strengthened EpiData Entry with several alternative mechanisms to try to avoid problems in this situation (e.g. only one record at a time is in memory. The rest is on the harddisk or floppy.). But despite this the error have been reported at rare instances. Also over the years I have seen files from this situation which was a combination of a rec datafile, a word document and a presentation or drawing. In other words this is part of a operating system problem. How to resolve ? If a corrupted file message is given you can do the following: Manual repair of corrupt files: 1 Make a second copy of your REC and CHK files and do the following (MAKE SURE IT IS A COPY !!!): 2. Verify that YOU HAVE THE ORIGINAL CORRUPTED file in a separate place. 3 Open the extra copy of the REC file in any ascii editor (e.g. notepad.exe). 4 Make sure you are using a fixed font. 5 Look for records with strange or odd formatted records and delete the complete record (Make a note of which one such that you can re-enter it later in EpiData) 6 Delete the parts with a strange format. 7 Pay particular notion to length of lines. All records should show same pattern. 8 Save the file and try to open in EpiData. If you think the above is hopeless - then try to regain other documents or files that were also open at the time, e.g a spreadsheet, a text document or a database from another programme than EpiData. The above is a modifed version of a user supplied explanation earlier. Regards Jens Lauritsen EpiData Association

How to: Recover "epidata rec files" or get sufficient help from others.
by epidata-list＠lists.umanitoba.ca 11 Oct '05

11 Oct '05

A good recovery strategy when something goes wrong is: 1. Ask yourself "When was I in control the last time" 2. What did I do since I was in control of the situation. 3. What might I have done wrong since the control. 4. What was I intending to do at the time when I felt no longer in control of the situation. 5. Do I think the "loss of control" is due to a software error, a hardware (e.g. harddisk broken) error or a user error ? 6. How much work should I repeat to continue working from my last backup of all data (I assume you do have a copy somewhere). 7. Can I repeat the steps from the "in control situation" to the "out of control situation" and the same thing happens every time. If you can answer these questions you have a very good clue for the solution or the appropriate information to tell someone who can assist you - e.g. other users on this list.

Good Colleagues Although I did not manage to catch who downloaded the number 1000 of analysis after release of v1.0 I think it is worth mentioning. It seems like the product is being received quite well. Regards Jens Lauritsen EpiData Association

How to: What do I do when Installation says "Unknown Publisher"
by epidata-list＠lists.umanitoba.ca 06 Oct '05

06 Oct '05

With Windows XP a new system has been invoked where software developers can add certificates to the software making sure from where a certain software comes. To get such a certificate for EpiData costs some funding. Maybe it is worthwhile paying and maybe not. Another "running cost" without other aspect than having an external certification office, e.g. verisign telling that software from http://www.epidata.dk is certified to come from epidata.dk is maybe not needed. What users can do to certify that there is no problem in installing EpiData software and be sure that there is no problem with this is: 1. Always get copies of software directly from Http://www.epidata.dk 2. Add "Http://www.epidata.dk" to "trusted websites" in 2a - firewall 2b - instllation policy of the individual user PC 2c - installation and software policy of the institution. Until someone finds a "software publisher certificate" essential and wishes to fund the issuing of a certificate I think funding is better spent on development. So in short: When the installation message says "Unknown publisher" - if you downloaded the software from Http://www.epidata.dk/download.php you can say yes to the install. If your system prevents this, then follow the advice points 2a-2c and try again. Kind regards Jens Lauritsen EpiData Association ps. Very few bugs have been documented in analysis. In the solving of those present undocumented updated versions for testing will be available as www.epidata.dk/downloads/setupepidatastattest.exe When a coming build is available for test this will be mentioned at the test page as usual- avialable through the link on the left side of the main menu.

Double Entry problem with range control in last field/variable on form
by epidata-list＠lists.umanitoba.ca 01 Oct '05

01 Oct '05

With the very precise description: "Does anyone know of a workaround that would allow me to preserve error checking on the last variable without encountering this problem (short of changing the order the questions, which would confuse data enterers)...perhaps a way to hard code a record advance into the check file? " With such a precise formulation it is possible to remove the error - not by workaround. In other words - the discussion on the list is very important to outline problems and find where the exact cause of a problem is. When a precise reproducible description can be made - this points to a specific part of the programme which can then be fixed. The fix will be part of next release of epidata entry.

"Anova = Means command" in Epidata V.1Rel.1
by epidata-list＠lists.umanitoba.ca 15 Sep '05

15 Sep '05

Hello , For comparing "means" of two independent samples , Epidata performs Anova (= t-test). But it assumes that the two samples have equal variances.( I have compared the results of Epidata with SPSS and Epiinfo).It does Bartlett's test and the result of this test ,say, shows that two samples have unequal variances but it doesn't notice to Bartlett's test ! Then why does it do Bartlett's test ? ( In SPSS , for comparing two independent samples ,Levene's test is done first and then we can interpret our results for "means" according to the result for Levene's test. In Epiinfo , Bartlett's test is done and if it is significant , Kruskal-Wallis is done. ) Thanks Reza --------------------------------- Yahoo! for Good Click here to donate to the Hurricane Katrina relief effort.

Re calculation formula
by epidata-list＠lists.umanitoba.ca 14 Sep '05

14 Sep '05

Hello! I need to calculate the sum of hours and days, in form of hours. So I did the formula as : total hours = days*24 + hours So when you have one day of time to be registered, and you have no umber of hours (i.e. zero), it is writting as "00" (two digits of zeros), then the "total hours" would give answer as "0", even though the number 1 is writting in days. When I triy to write the zero, as one digit (i.e. "0"), then it works fine. Any tip how to overcome it? Here is below a copy of the formula: d8 MUSTENTER AFTER ENTRY LET d10=d9*24 + d8 END END Thank you in advance! /Ziad -- Ziad El-Khatib Division of International Health Care and Research (IHCAR) Department of Public Health Sciences Karolinska Institutet

Hi; It all depends of the analysis version you are using. 1- from Epi 6 Analysis, the simplest way is to send results to an external text file that you can then edit with any text editor or word processor. ROUTE xxxx.txt TABLES AAAA BBBB TABLES CCCC BBBB ... ROUTE (the last route closes the file, so it can be handled by another program) Then, open the text file with Wordpad, Word... 2- From EpiData Analysis, use the command 'logopen', give a name to the file (e.g. logopen TEST); a file named TEST.HTM is created, containing all results produced (tables, graphs...). It can be opened with any web browser, or edited with Word, for example. Best regards, ______________________________________________ Gilles DELMAS Institut de Veille Sanitaire Dept.

hidden values, but aggregate counts?
by epidata-list＠lists.umanitoba.ca 30 Aug '05

30 Aug '05

First, my thanks to Dirk for answering an earlier query of mine. Please forgive another question. For each record, I calculate a value at the bottom of the data entry form and determine if the respondent fits in group 1 or group 2. Is there any way to hide this group designation for the individual record (as in the value cannot be seen in the form), but still count the aggregate number of respondents fitting into group 1 or group 2? I consider using a temporary variable as a counter, but this raises complications if records are entered in separate batches or earlier records have their values modified. Thanks! Anthony

Double Entry Verification and several fields to match on
by epidata-list＠lists.umanitoba.ca 26 Aug '05

26 Aug '05

> [EpiData-list] verification question >>> [1] I would like to MATCH RECORDS by more than ONE FIELD when >>> preparing double entry verification - is this possible ? >>> [2] Once a file is verified, does the corrected data reside in the >>> *.REC or the *_dbl.REC file ? EpiData has two principles of validation: A. Compare two separate files entered independently. B. Compare at field level while entering data. Preparation of the two are both at the tool menu. A. Copy structure (of existing rec + chk file) B. Prepare Double Entry Verification Actual validation: A. Is done after all data have been entered. In the document menu you can "Validate Duplicate Files". When you specify the two files up to three fields can be used to match the two files. B. Is done while entering data the second time. You can only match on one field. The corrected data resides in the ..._dbl.rec file, which is the one you are adding data to. After point B you can run the two files with option A and get a record of how much was corrected while entering data the second time in ..._dbl.rec file. If you want to create a unique match while entering data on more than one field a typical way of doing so would be to create a key field like this: To do so, e.g. your matching fields are v1 v2 v3 in the check file: v1 mustenter end v2 mustenter end v3 mustenter after entry keyfield = string(v1)+" "+string(v2)+" "+string(v3) end keyfield noenter key unique end I am not sure how double entry would handle this, but make a test and see how it works. regards Jens Lauritsen EpiData Association

Analysis build 36 released
by epidata-list＠lists.umanitoba.ca 25 Aug '05

25 Aug '05

Analysis build 36 was just released for testing. at http://www.epidata.dk/testing.php Unless users report severe problems, the current build will be released as version 1.0 with some restrictions or removal of commands with problems, see below. Version 0.9 release 5 build 36 * Added or modified o A "select font" on first startup to guide the user for efficient setup of screen o Improved documentation of output formation o Table command can show categories defined as missing o New option controls if more than one instance of the programme can run o Aspects of handling missing value further implemented. o Parsing of strings changed to exclude trailing blanks: e.g "Lion " is the same as "Lion", but not the same as " Lion". o sorting of tables corrected o Tests of homegenity (interaction) in summary stratified 2x2 tables removed until final stable solution is found * Bugs fixed: o "Pointer error" in tables, graphs or describe fixed o Error in table estimates for 2x2 tables o Recnumber now returns number within current select o set listrec was not working Remaining known major issues to settle before v1.0 * Tables must be included in txt formatted log files Known major issues not settled or clarified * Relating files not tested fully * Appending in combination with records marked for deletion * Odds Ratios and RR in tables with Rare data (0 in cells) * Tests of homegenity (interaction) in summary stratified 2x2 tables removed until final stable solution is found Known issues not fixed (put on future list) * Correlate command results in "floating point error" when correlate cannot be calculated * Contents of strings should be converted to UPPER in logical statements to work. e.g. count if upper(v) = "TEST" * Setting format (set number format) is not consistent Kind regards Jens Lauritsen

[1] I would like to MATCH RECORDS by more than ONE FIELD when preparing double entry verification - is this possible ? And if so, how do I do it ? [2] Once a file is verified, does the corrected data reside in the *.REC or the *_dbl.REC file ? Thank you.

Re: protecting formulas in check file?

You cannot protect the chk-file completely (e.g. against someone determined to change its contents), but you can protect it from accidental changes it by setting the read-only flag of the file (see "file attributes" of your operating system).

I have some coefficient values and equations in my chk file and I wondered if there was some way to protect them from being changed by another user down the road? In other words, can I structure it so somone in the field can enter the data into the form but not manipulate, accidentally or otherwise, the chk file contents? Any help would be much appreciated.

Why does calculation of age at given date not work ?
by epidata-list＠lists.umanitoba.ca 09 Aug '05

09 Aug '05

Question sent to info(a)epidata.dk: I wrote commands as following, which I follow the help commands: dob AFTER ENTRY LET age=round(int(("1997/11/01"-dob)/365.25)) END END But when I change "1997/11/01" into today, as in the following commands, it works! Why so? dob AFTER ENTRY LET age=round(int((today-dob)/365.25)) END END So I just want to ask what is the problem, because I strictly followed your commands in help manual, but age cannot be calculated on a given date. The formulations above are correct, with one exception. THe help file says also: EpiData was made in Europe and here dates are written in the notation dd/mm/yyyy, so to make the statements above work LET age=round(int(("1997/11/01"-dob)/365.25)) should be: LET age=round(int(("01/11/1997"-dob)/365.25)) regardless of which format dob has. It is better to send questions like this to the EpiData list at: epidata-list(a)lists.umanitoba.ca, since the info @ epidata.dk is very often overly filled with spam mails.

To see value labels you need not (only) the question file (.qes) but the records validation file, as well. One possibility for the different results you obtain is that the validation file (.chk) is not always in the directory EpiData expects it to be - EpiData lets you enter data, create a codebook etc. even if no validation file exists (or if the validation file is in a different directory as the records file .rec). In that case, however, no value labels can be applied. Dirk Cahterine Mathews (epidata-list-request(a)lists.umanitoba.ca) wrote: > Hi > We're using version 3.1, downloaded from the Epi Data site.

data labels

Hi We're using version 3.1, downloaded from the Epi Data site. This is the first time we've used Epi Data. We are in the process of entering data into it. Initally, when we created a codebook from the QES file, the codebook displayed the values together with the value labels. But in subsequent attempts to create a codebook from the same QES file, we have found that the codebook won't show the value labels we entered into the QES file. Sometimes it won't even show the values. Do you have any ideas about this? Thanks! Catherine Mathews School of Public Health and Family Medicine University of Cape Town

Status of EpiData Analysis development
by epidata-list＠lists.umanitoba.ca 08 Jul '05

08 Jul '05

Since release of first public test build of analysis in october last year good progress has been made. In judging progress it is important to recognize the nature of the EpiData Association, the size of economic contributions for development and the pricing principle - freeware. The latest build is available from http://www.epidata.dk/testing.php The list of what is fixed and remaing by build number is seen at: http://www.epidata.dk/analysisinfo/docs/versioninfo.htm The bug reporting database is shown at: http://asp.epidata.dk/support/default.asp The routine tests now include more than 350 conditions looking at as well overall, stratified and segmented conditions and comparing to external standard estimates. The aim of the complete test suite is to certify all available commands for a chosen number of representative datasets. The definite condition to meet before release is that the quality system certifies as well stability as correctness of estimation. But also that the implemented principles are logical in structure and documented such that decisions and requirements are clear to the end user. An example of this is the latest preparation of a detailed description of the principles of the output implementation of html and style sheets. The number of combinations of font selection, sizes and character sets is very large requiring control at the level of the end-user. This is available now, but for persons with very little or no knowledge in HTML and stylesheet principles the control of output can be a mystery. The status list includes : a. The main design principle of user interface, output formulation, number of commands, principle of missing data is final and most of it working. b.Finalisation of a simple way for users to define interface with local fonts etc. as part of the installation is almost finished. c. A coherent strategy for handling missing values across commands is being implemented. d. Some issues of table estimation exist. E.g. with correct turning of outcome and exposure. Some "Floating point and "Pointer" error messages occurs with some combinations of data e. Some aspects of graphing are giving problems. (Also relates to point b) Re c: e.g. if the user requests frequency tables for say 5 variables: 1. freq a b c d e 2. freq a b c d e /nomissing the first will show all data for all records, whereas the second will demand complete data for all five variables. This principle should be the same across all commands. And the implementation is needed as part of the testing of handling the data correctly.

This seems to be a random occurrence. Closing the file and starting data entry again has solved the problem for me. 2. The problem of EpiData skipping a field after using [-] to enter a missing value can be addressed for now by checking whether the skipped field is blank before proceeding (see below). This problem only arises when the default missing value has the maximum number of digits in a numeric field. In Dirk's case, missing value is 9997 or 9999 in a #### field. Another solution is to make these special missing value codes negative numbers (e.g. -1) or smaller numbers (e.g. 999), which will be smaller than the field size. Then there is no skipping. This problem does not occur with fields of length one.

Problems with [-] key for entering missing values
by epidata-list＠lists.umanitoba.ca 03 Jul '05

03 Jul '05

Using the following .qes and .chk files with EpiData version 3.1, EpiData's behavior is strange: If I use the [-] numeric key to enter missing values in the field "schtype", EpiData jumps to the field "male" (i.e. "class" receives no focus). If I use the [-] key in field "male", EpiData issues the error message "'-' is not a valid floating point value" although missing values are defined. The problem seems to be the movement to the next field after using the [-] key, because if I drop field "coder" the problem of field "male" does not occur. Is there a problem in the check file I did overlook or is this a problem of EpiData version 3.1? Are there any solutions/suggestions? BTW: Unfortunately, if I want to label the missing values (an important feedback to the coder in case different types of "missingness") I cannot utilize the facility of EpiData to use the [-] key for entering missing values, because I cannot (better: should not) use COMMAND LEGAL and MISSINGVALUE with overlapping sets of values for the same field. This underscores the importance of the suggestions in my last mail (July 1, 2005) to the list.

Bug in EpiData 3.1? (TYPE STATUSBAR)
by epidata-list＠lists.umanitoba.ca 01 Jul '05

01 Jul '05

I noticed some differences between EpiData 3.0 and 3.1 and a possible bug in version 3.1: 1) If I use the check command TYE STATUSBAR "CaseNum = " the value of the field (here: casenum) is only shown in the statusbar if the focus is on the field. If I move to other fields, the value is not visible anymore. This occurs in version 3.1 but not in 3.0. This seems to be an error of version 3.1. 2) Version 3.0 and 3.1 differ in the way they display values defined by RANGE, MISSINGVALUE, and/or COMMAND LEGAL (field). For example, I have a multiple response question and the first question is a filter (if checked, the following multiple response questions do not apply). Or there is no filter variable but I want that the coder first has to decide whether any of the multiple response questions are checked (this is what I use in the following example). If not, I want that all values are set to missing (9 - no answer) and the focus should be set to the next block of questions. On the other hand, if there is at least one answer checked, the focus should move to the first of the multiple response questions and the user has to enter one of the folling values: 0 (no checked), 1 (checked), or 7 (ambiguous answer). When all data are entered, I want that the value labels are defined as follows (because I want that the SPSS syntax attaches value labels to missing values, as well; 8 is necesseary because the whole block of questions may not be applicable): * --------------------------------------- LABEL notice 0 "somebody found out" 1 "nobody found out" 7 "ambiguous answer" 8 "not applicable" 9 "no answer" END * --------------------------------------- However, to help the coder I want that while entering the data he/she does not see these labels but the following: ----------------------------------------- 0 - (not checked) 1 - no 7 - (ambiguous answer) ----------------------------------------- With EpiData version 3.0 this is possible if I use the following check commands: * ======================================= beerdt MISSINGVALUE 9 8 7 * <- (1) BEFORE ENTRY HELP "MULTIPLE RESPONSE QUESTION\n\nQuestion 46.6: Anything checked? (y/n)" KEYS="YN" IF (RESULTVALUE=2) THEN beerdt=9 beerdtpa=9 beerdtpo=9 beerdtte=9 beerdtse=9 GOTO beerpun ENDIF COMMENT LEGAL SHOW * <- (2) 0 "(not checked)" 1 no 7 "(ambiguous answer)" END END COMMENT LEGAL USE notice * <- (3) MUSTENTER TYPE COMMENT RED JUMPS 1 beerpun 9 beerpun END AFTER ENTRY IF (beerdt=0) THEN clear beerdtpa clear beerdtpo clear beerdtte clear beerdtse ENDIF IF (beerdt=1) THEN beerdtpa=0 beerdtpo=0 beerdtte=0 beerdtse=0 ENDIF IF (beerdt = 7) THEN WRITENOTE "ambiguous answer" ENDIF IF (beerdt=9) THEN beerdtpa=9 beerdtpo=9 beerdtte=9 beerdtse=9 ENDIF END END * ======================================= However, with EpiData 3.1, I cannot use "MISSINGVALUE 9 8 7" (see: * <- (1)) _and_ "COMMAND LEGAL SHOW" (see: * <- (2)) or "COMMAND LEGAL notice" (see: * <- (3)) simultaneously. If I use (1) and (2), the user sees: ---------------------- 0 - (not checked) 1 - no 7 - (ambiguous answer) 9 - missing 8 - missing 7 - missing ---------------------- and is able to enter 9 (which should not be used) or 8 (which would be wrong). If I only use (2), the value (9) or (8) cannot be set by the "BEFORE ENTRY .. END" command or by an IF .. THEN condition in another field. To use (3) would also be no solution to this problem. Thus, only version 3.0 seems to allow a solution to this problem. My main question is: Are there any reasons why I should prefer version 3.1 to version 3.0? Or which check commands do I need to solve the problem in version 3.1? With respect to the missing values it would be extemely helpful if EpiData could create SPSS syntax that defines missing values according to the definitions in the EpiData check file. However, if (like in version 3.1) I cannot use MISSINGVALUE and "COMMAND LEGAL labelname" (because I want to label the missing values and to show the coder the meaning of the values entered) simultaneously , there are no missing value definitions that EpiData could use to create the SPSS syntax file. I think that there are two solutions to this problem: (1) If MISSINGVALUE and "COMMAND LEGAL labelname" are used simultaneously, in displaying the legal values the values defined in the LABEL block get priority (and values MISSINGVALUE are not duplicated in the display). This would solve the problem described above, as well. (2) Alternatively, if the MISSINGVALUE is commented out EpiData uses only the values defined by RANGE or COMMAND LEGAL, but uses the values defined by the MISSINGVALUE command that is preceded by "*" for creating the missing value definition in the SPSS syntax. For example: * ---------------------------------------- LABELBLOCK LABEL variable 1 no 2 yes 8 "not applicable" 9 "no answer" END END variable COMMENT LEGAL variable * MISSINGVALUE 9 8 END * ---------------------------------------- would create the following SPSS syntax: * ---------------------------------------- VALUE LABELS variable (1) 'no' (2) 'yes' (8) 'not applicable' (9) 'no answer'. MISSING VALUES variable (9,8). * ---------------------------------------- Regards, Dirk ************************************************* Dr. Dirk Enzmann Institute of Criminal Sciences Dept. of Criminology Edmund-Siemers-Allee 1 D-20146 Hamburg Germany phone: +49-040-42838.7498 (office) +49-040-42838.4591 (Billon) fax: +49-040-42838.2344 email: dirk.enzmann(a)jura.uni-hamburg.de www: http://www2.jura.uni-hamburg.de/instkrim/kriminologie/Mitarbeiter/Enzmann/E… *************************************************

Export to SPSS, Variable names
by epidata-list＠lists.umanitoba.ca 24 Jun '05

24 Jun '05

Hello, I have a suggestion for the Epidata-Help-File, section "Export to SPSS": In Epidata you can use variable names (or field names) with a maximum of 10 characters. In newer versions of SPSS (12 or 13) you can use long variable names (64 Byte = 64 characters), in older versions only 8 characters. Exporting Epidata-fields with 10 characters to SPSS leads to shortened field names with 8 characters (for SPSS before Version 12). That causes a lot of work (e.g. renaming variables), if you think that 10 characters are exported. A hint in the Epidata-Help, that if the Data will be analysed in SPSS, the field names should have max. 8 characters, will be usefull.

How to: Change id variable type from numerical to string
by epidata-list＠lists.umanitoba.ca 17 Jun '05

17 Jun '05

A question that came to epidata.dk: > In our EPI test.rec file we have made a 'clientnumber' field for a > maximum of 7 numbers entry (#######), for example to enter > clientnumber 3458. This test.rec file contains now several records. > But now we need to use the same field for entering a letters and > digits combination, f.e. P3467188. > I realise that we should have designed a string field <a >>. > > The clientnumber field not only needs to be longer than 7 numbers but > should be suitable for letters as well. > > Is it possible to change that in our current test.rec file? We prefer > that over making a new .qes file and an empty .rec file. > This is of general interest. the solution: 0. Make sure you have proper backup in case something goes wrong. 1. Either add a new field in the qes file with the letter part add a new field for combined letter + number add 2. or make qes and change to string field the same field update the rec file (just enter and epidata will ask ) 3. If you wish to add a certain letter to all previously added records add a recode block to the chk file or other file and run recode from the tools menu. See help file on recode e.g. if new string type id field is idNew and the old numerical one is id recodeblock idletter = "F" idnew = idletter + string(id) end plus to accomplish future records in same file: idnew noenter end idletter mustenter end id mustenter after entry idnew = idletter + string(id) end end -- Jens Lauritsen Coordinator and initiator of EpiData Project http://www.epidata.dk

RE: selecting on string variables

>>> <epidata-list(a)lists.umanitoba.ca> 25-05-2005 16:59:11 >>> Why is this necessary? I see "LION", upper case and delineated with " ". Thanks, Kelly Because assigning this : if recnumber = 2 then animal = "LION" to a stringvariable of length 10 gets the value: "LION " not the value "LION" Computers are stupid and the designer makes the choices. My choice is that "LION " is different than "LION" Someone would argue that we should always use the trimmed value of string variables, such that "LION " is the same as "LION" but this would give the user a problem if he/she wanted to compare the full length string. The strategy of EpiData for as well data entry as the coming release of analysis is that we make as few decisions as possible and let the end user decide. This is in contrast to other software developers who often impose new and changed strategies and changed ways of doing things on the users (Who is then forced to keep upgrading and learning new ways of doing what they could do with the old principle). EpiData tries NOT to invent new ways of doing things, but stick to the well founded principles of Epi6 (with appropriate extensions for those who wish to use the new principles of further documentation).

Topics in EpiData-List
by epidata-list＠lists.umanitoba.ca 02 Jun '05

02 Jun '05

The EpiData-list has been set up with two topics today: Analysis Data Entry A topic is a way to selectively receive only part of the mails from the discussion list. By default ALL mails are sent to all users. Even annoying ones, such as when I forgot to turn off an "out of office" message to the list last week (excuses) and all users received a message in Danish. How does topics work ? If a user is signed up to only "analysis", then only mails which contain the word "analysis" in the subject line or the first 15 lines of text in the body of the message will be sent to that user. If you wish to receive all mail: You do not have to do anything. If you wish to select only mails for one or the other topic: Go to this page in your browser http://lists.umanitoba.ca/mailman/options/epidata-list and edit your user profile. Further information is given on that page. For all users it is always good practice to choose wording of the subject such that other users can see what this mail is about. This is particularly true when topics are in effect. Regarding release of analysis I can inform you that we are progressing, but some errors in the basic handling of selecting data has postponed the release. The problem is related to a valid way of separating float values, such as e.g. 3.1 from 3.100000000001 and 3.097865491 Jens Lauritsen Coordinator and initiator of EpiData Project http://www.epidata.dk

Hi! The 3 variables (Day, Month and Year) have to be string (or at least, it works that way!) Assuming following variable names : Date: DATE, Day: DAY, Month: MONTH, Year: YEAR) In the After entry block of the date variable, place the lines below: DAY = day(DATE) MONTH = month(DATE) YEAR = year(DATE) Day, month and year are functions which automatically extract the corresponding values.

How to select "string variables" in Epidata Analysis ?
by epidata-list＠lists.umanitoba.ca 01 May '05

Dear sir, Hello. I am one of Epidata Users around the world. I can not select "string variables" by Epidata Analysis. I am not sure whether the "Epidata Analysis" program can select string variables. For example: Name of my Variable : Outcome and my Options for the variable : cure , death , disabled, unknown I write(or do) the command: select outcome="death" But no selection is done and this is the massage : No records available But I am sure that records are available because I myself have entered them and also EpiInfo software do select them !

Epidata: "Error reading record"
by epidata-list＠lists.umanitoba.ca 14 Apr '05

14 Apr '05

Hello everybody, I sometimes get an error message "Error reading record" when I open an Epidata *.rec file. Sometimes it happens by opening the whole file (I can't open it), sometimes only, when I try to access the last entered record. When I export a data file with this error message (i.e. to SPSS), all records are exported correctly, nothing is lost (as far as I can see). I believe, that this error only happens with data files that I received as email-attachments. Is it possible, that sending *.rec-files by email "destroys" something in the file structure? Any suggestions how to avoid this problem? Thanks for help Juergen Spiegel *********************************************** Freiburger Institut fuer angewandte Sozialwissenschaft e.V.

Relate is a very complex system. So to change structure of files in the middle of loading is a potentially error resulting situation. But I agree that the user should be warned somehow.

Menu systems with EpiData
by epidata-list＠lists.umanitoba.ca 06 Apr '05

06 Apr '05

Kelly wrote yesterday that it would be relevant to create menu systems such as in Epi6. One way to do this would be to create in EpIData Analysis a new html file. Look at the info.htm supplied with the test version now available at http://www.epidata.dk/testing.php As part of this page there are three links looking like this: Examples of how the programme works: Graph: "Bar chart" (Click) "Statistical Process Control Chart" (Click) "Descriptive Means and descriptives" (Click) If you load the info.htm file into the editor of EpiData Analysis (press Viewer on the process toolbar and "edit HTML output" then you will see that behind the three links are actual commands, e.g. the link behind "Bar Chart" Contains: <A HREF='epi:CLS;close;set echo=off;define fn __________________________ glob;fn= "@sysdir"+"testdata";cd "@fn";read bromar;set warning=on;bar agegrp;cd; set command=off;echo Press F1 to view info again;set echo=on'>Bar chart</a> (Click) So even this looks a bit complicated you can see that it is ordinary commands, such as define fn ____________ global read bromar bar agegrp So to build a menu system that does analysis you could either have in the link: <a href=epi:'run myprogram.pgm'>do the analysis</a> or add the actual commands contained in the "myprogram.pgm" file separeted by semicolons. Users are encouraged to experiment with this type of developments. Examples could then be placed on the examples page of epidata.dk To facilitate such menu or analysis systems EpiData Analysis has been made such that almost all parts of the interface can be turned off, e.g. the main menu, toolbars or the command prompt.

Command line and demonstration
by epidata-list＠lists.umanitoba.ca 06 Apr '05

06 Apr '05

Greetings. 2 things. 1. I saw an example from Epidata which looked like this: c:\epidata\epidatastat myreport.pgm I haven't tried this but, does this mean that epidatastat will execute the .pgm??? I would lke to see all components of EpiData, analysis, editor etc. to be Able to for example: EpiENTER <file.rec>, EpiEDITOR <*.pgm>, EpiSIS <myreport.pgm> etc. Why? When developing systems using MENUs it seems to be better to 'hide' from the General user the database, reports .pgm etc. Selecting EpiData and then option 4 Exposes databases etc. to perhaps a not so sophisticated user. 2. I work for the CDC/Global AIDS Program and I think I have managed folks to Investigate placing EpiData, analysis etc. into what we call a software development Tool kit. I have been asked if I would conduct a 'brown bag' demonstration etc. I do not think I have enough experience as yet to do the software justice, expecially Analysis. Is there someone out there who would like to discuss this with me? Thanks and stay safe, kelly

How to import and restructure data and create a report every month in an easy way ?
by epidata-list＠lists.umanitoba.ca 05 Apr '05

05 Apr '05

Someone asked off line how to accomplish this If you have to restructure files often based on the same qes file the revision of structure can be saved as EpiC commands in a batch or command file (e.g. revise.cmd) See the documentation for EpiC for further instructions, e.g.: EpiC revise newqes.qes datafile.rec FIRST FORCE LOG="what_happended.log" Would revise the file "datafile.rec" based on contents of "newqes.qes" and force restructuring regardless of this would mean loosing fields (Option FORCE). The results are saved to the log file "what_happended.log" EpiC can do other parts also, e.g. create or open a zip archive or encrypt (decrypt) files. EpiC is available from the download page of http://www.EpiData.dk Example: Assume you recieve files with administrative data every month called datafile1.txt datafile2.txt datafile3.txt To import these data, make control lists and prepare a reports you do this: Create - a file called structure.qes which contains the same format for fields as the txt file with administrative data. - a file called newstructure.qes containing the fields you wish to keep in an approriate format. - a file called report.pgm which will in analysis append the three files and make a standard report. Then create the file revise.cmd with this content: *.......revise.cmd .................................................................... EpiC revise newqes.qes datafile.rec FIRST FORCE LOG="what_happended.log" EpiC import TXT datafile1.txt qes=structure.qes out=datafile1.rec delim=; q=text ignorefirst date=yymmdd EpiC import TXT datafile2.txt qes=structure.qes out=datafile1.rec delim=; q=text ignorefirst date=yymmdd EpiC import TXT datafile3.txt qes=structure.qes out=datafile1.rec delim=; q=text ignorefirst date=yymmdd EpiC revise newstructure.qes datafile1.rec FIRST FORCE LOG="what_happended.log" EpiC revise newstructure.qes datafile2.rec FIRST FORCE LOG="what_happended.log" EpiC revise newstructure.qes datafile3.rec FIRST FORCE LOG="what_happended.log" * then you could make a list of data from the centers involved: EpiC count center datafile1 datafile2 datafile3 LOG="centerlist"] *You could also export datafile1 to a spreadsheet format for the center with number 276 for particular checks: EpiC e xls datafile1.rec datacenter276.xls filter="CENTER=276" * and finally you could make a standard report using analysis: c:\program\epidata\epidatastat myreport.pgm .............................revise.cmd to here You would then only have to start the revise.cmd to create your monthly report.

How to change a field to encrypted form in an easy way ?
by epidata-list＠lists.umanitoba.ca 05 Apr '05

05 Apr '05

Someone asked off line how to accomplish this Situation: You have a file with say 1000 observations and you wish to encrypt the field containing social service numbers: 1. use epidata to make a qes file (tools menu - qes file from recfile) 2. edit the field in question from e.g. string field : v1 social id __________________________ to v1 social id <e > (same length) numerical: v1 social id ######################## to v1 social id <e > 3. Save the qes file 4. start enter data (point 4 on work process toolbar) and EpiData asks if you wish to update based on the revised qes file. 5. Do so and you are asked for passwords Thats all.

Setting up user rights in Windows XP can be very troublesome. It is not possible to give general advice for this, since there are very many local policies. In some places users have no rights at all, in other restricted access to one folder, ...... The EpiData programme as such does not read any of these rights and can be freely copied from one folder, memory stick or CD-rom or moved without "real installation", since the registry access is not part of the installation (unless you decide to associate file types with epidata). To work with rec and qes files the users need write access rights in that folder. So instruct the users to work on their default data folder - e.g. this could be "C:\documents and settings\mdi256\documents". But to share files btw. users you would need common rights to that folder. Also the file "epidata.ini" is saved after running epidata with current settings of screen, options etc. So the user needs write rigths for that or an error message box will appear at closing of EpiData. So in general: a. Let each user install epidata in their own data space (it is only around 2-4Mb for the whole programme) and each user can work independently. b Set up your pc such that each user have sufficient rights Jens Lauritsen Initiator and Coordinator of EpiData EpiData Association

Why Can I not use labels from EpiData in Epi Info for windows

I want > to know what to do to keep these labels. > Sylvie Delcroix, France Epi Info for windows from CDC does not use labels. This is part of the reason I started EpiData, because in analysis the labels are crucial as documentation. If you want to use the labels in analysis you will have to use EpiData Analysis which is getting closer to release. If your analysis is general crosstables, descriptive statistics and graphs the test version available at http://www.epidata.dk/testing.php will do the work for you. You could decide the strategy: 1. Do the basic analysis you have to do anyway with EpiData Analysis. 2. If you need to do further advanced analysis do the rest in Epi Info for windows (or other software) Regards Jens Lauritsen EpiData Association

But in Windows XP or XP-Pro when run as normal User (NOT Administrator) , EPIDATA refuses to open files (QES or REC) While running as ADMINISTRATOR, everything works OK ! Any suggestion or fix .. thanks in advance and many thanks to the creators of EPIDATA.

Re: EpiData - JUMPS involving calculations

You do not use the JUMP command, but rather use the logic you show in your message. Use the Edit button in the Check screen and type in the if statement. You have access to many useful functions as well - in this case the ABSolute value function. There are good examples in the help file accessible from within EpiData.

How to insert calculation in JUMP add/revise check
by epidata-list＠lists.umanitoba.ca 15 Mar '05

15 Mar '05

I am a new EpiData user. I am creating a data entry screen for anthropometric data. There are two weight measurements - and a third if the first two differ by +/- 0.5 kg. How can I incorporate this calculation in the JUMP section of the Add/Revise Checks so (1) if WT1 - WT2 GE 0.5 OR LE -0.5 go to WT3 (2) else go to HT1 [the next field] Thank you.

Re:Search problem

Could the problem be that the search is just marked as say 'forward' and you are sometimes already past the record you search for? Then marked 'search all records' instead or go to record 1 first.
