EpiData statistics documentation.

Lu 30 mai 2011 Hello EpiData users, I'm a new subscriber to this list. I used recently EpiData Analysis for a matched case-control with a controls:case ratio of 38:19 or 2:1 (TAB DISEASE EXPOSURE COMMONID /O /t /ex). In the results output, and in the online help, for the crude table, I could'nt find the type of test used, for example, which kind of Chi-square (I was able to deduced it was uncorrected), of odds ratio (maximun likelihoodestimate [MLE]?) and associated confidence interval (95%?), and Fishers exact test (bilateral?). In the adjusted table, the OR [MLE?] is provided with a CI (MLE and 95%?), followed by a Chi-square (unspecified kind) and another p value (which kind?). The provided p values are rounded at 3 digits after the decimal point. The last column provide p-exact values (Fishers?), and the one on the adjusted line seems to refer to another Chi-squared provided at the bottom of the table. Finally, the exact p value for the adjusted results (e.g.: 0.3140) doesn't match with the "probability of MLE >= value of MLE of OR (e.g. 6.10) if population OR = 1.0" that I obtain (e.g..: 0.00196) with the command MATCH COMMONID DISEASE EXPOSURE of Epi Info 6.04d DOS (which is probably equivalent to an exact test), and seem discordant with the values of the CI (e.g.: 1.62 to 34.17). Using the cohort approach (TAB DISEASE EXPOSURE /RR /t /ex), I found similar lack of documentation about statistical tests. I would suggest the following to the conceptors of EpiData: - provide some documentation about statistical tests used in Analysis (do any of the users have those answers?); - provide notes at the bottom of tables to eliminate any ambiguities about statistical methods; - provide p values in the ajusted table with 4 digits after the decimal point. This software work pretty well, but need some ajustments. Keep on the good work.

Updated Manager and EntryClient available for testing
by epidata-list＠lists.umanitoba.ca 06 May '11

06 May '11

Dear All. An update version of the Manager and EntryClient is available for download on http://www.epidata.dk/testing.php This release is mainly focus on adding new features for controlling field entry, but does also include some rare-case bugfixes. Dues to changes in the project file structure, loading .epx/.epz files from previous versions of Manager and EntryClient will not be possible. However, we do hope that with the added features of todays test releases, we are very close to a settled "version 1" of the project file structure. As always, an updated version of the sample file is included in the downloads. The major changes for both Manager and Entry client are: 1. Fields may have notes attached. These are written in the Manager and can be read in EntryClient using F12. 2. Write the label part of a ValueLabel to a string field. 3. Fields may have a default value. 4. Fields can repeat value from previous record. 5. Simple calcaulation may be performed on exiting fields. (In old epidata known as AFTER ENTRY). These calculations are limited to 3 different types: a) Calculate the difference in time between two dates and/or times. b) Create a date based on a day, month and year field (integers). c) Combine 1-3 fields into a string field. 6. Compare two fields and require entry to respect the comparison. Eg. DateField2 > DateField1. 7. Force EntryClient to show the list of valuelabels associated with a field (manually show by pressing F9/+). Changes related only to Manager: 1. Large rearrangement of the Field Properties form. We have tried to group most used properties and logically connected propertied together. 2. Added tool for packing dataset. Removes records marked for deletion (see below). 3. Added Study information to Project settings form. Changes related only to EntryClient: 1. Search functionality: Ctrl+Shift+F: Show search dialog. Ctrl+F: Show search dialog filled with current entry for record. Ctrl+L: Do NOT show search dialog, but search with current entry and display a list of matching records. F3: Repeat last search in forward direction. Shift+F3: Repeat last search in backwards direction. 2. Updated graphical interface of program settings (Alt+S). 3. Records may be marked for deletion. See buttons beside record number. Kind regards, Torsten Christiansen. EpiData Association.

Suggestion: To go forward relational database and complex jumps with Entry Client and Manager
by epidata-list＠lists.umanitoba.ca 03 May '11

03 May '11

Hello: Sometimes I find out a bug on the EpiData testing version of the EpiData Entry Client and the Manager, using GNU/Linux. We are having some days without a very difficult bug to appear on the version. So I suggest to the programming team to go forward other steps like: 1) Relational database function and interface 2) To a more complex way to make jumps and conditional entry.

My English is bad and I apologize for that. My research instrument contains 21 questions to be answered for 12 disciplines in a course. The number of respondents is approximately 100 people. Each question will be answered for all disciplines. I am attaching an example with three questions (one question for each file.) When finished entering the data of 12 disciplines in question 3, I want go to the file Quest which is the first issue, data entry of a new student. Note that I used the RELATE command in questions 1 and 2.

Dear Silvano Cesar da Costa, One reliable way to approach this is to close the files in reverse order until the edit pencil is pointed to the start(in your case may be file 1). *As general rule*: To enter data in relational database you must either move down the tree through the field that contains the Relate command, or move up the tree by closing the rec.files. On closing file21.rec the cursor should go back to file20.rec so on. Pressing F10 or CTRL+R ( return key) closes the file and moves the cursor/edit pencil back one level to the data files that called RELATE. Hope this would help.

Analysis: graph creating GUI bug?
by epidata-list＠lists.umanitoba.ca 30 Mar '11

30 Mar '11

Hello all, I noticed that the GUI which allows you to create histograms (Graph -> Histogram) does not let you specify a boolean variable as "by" variable. Example: . read C:\EpiData\TestData\bromar.rec . select dectime<>. . gen b fast=(dectime<3.87) it is possible to do the following: . his age /by=fast but the GUI form does not list "fast" as a "by" variable. Kind regards, Simon PS: I tried to report this on flyspray, but I get a "Error #23: User or group not enabled for login." when I try to log in.

New EpiData EntryClient version release for test
by epidata-list＠lists.umanitoba.ca 29 Mar '11

29 Mar '11

Dear List A new version of the EpiData EntryClient program have been release for testing today. Due to a significant bug in jumps, where the program would end up in an infinite loop, we have decided to release a new version where this problem is no longer present. Since the sample file contains a contruct that could activate this bug, we strongly recommend all using the old version of EpiData EntryClient (0.3.2.0) to update to the new version. With kind regards, Torsten Bonde Christiansen EpiData Association.
