Yesterday I uploaded a new test build for analysis, now build 118. Since previous test build many internal parts have been rewritten, such that the source code is the same where possible for analysis, entry and epic. Most of this is invisible to the end-user, but assures that e.g. chk files are read the same way in the systems. A few aspects remain btw. the products. e.g. naming of integer function int() versus integer(). Of particular interest to the end-user is the following: Practical: a. A new table dialog makes it easier (hopefully) to use the possibilities in the new table command without using the command prompt. The table dialog is available from the toolbar or as a command tabdialog. b. Graphs can now be made by a group variable. e.g. box age /by=sex will create two boxes for two values of sex c CHK files are now saved with the data. Including definitions of variable labels and missing values. d When looking at a table or graph in output, rightclicking with the mouse copies that table or graph to clipboard. (for tables sometimes there is a pointer error, but this will be fixed). Technical issues: a. No new functionality will be added before release as public v2.0 except for translation, which is about half way implemented. b. Bugs should be removed before releasing. - some issues are known and will be documented in the Mantis database c. We should decide what to do about text strings in rec files, which are found in the qes files, but not read into analysis. d. Translation for analysis is about half way e. the Mantis system is not completely updated, but this should take place within about a week to reflect what was fixed and what remains. f. There are still some minor estimation problems, such as percentiles not being correct with very small samples (e.g. n<15).

You are right Jamie - a response of 1 was given for most imporant. I will try using your v1=10-v1 and then the method Jens suggests. thank you very much to both you and Jens for your help Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list(a)lists.umanitoba.ca> 24/08/2007 1:33 p.m. >>> An important question is whether a response of 1 most important or least important? If 1 is most important, then make the default value 11 and not zero. I would just do: describe v1-v25 and scan the medians to find those with the lowest median (if 1 is most important and default is 11) or highest median (10 is most important and default is 0). Items that are infrequently ranked will have a median equal to the default. Items most frequently ranked will have a median that is based mostly on ranks. I haven't thought about the formal statistical analysis here, but you'll get a pretty good assessment. Jens approach works very well when the most important response is 10. If most important is 1, then you can also do this: v1 = 10-v1 v2 = 10- v2 etc and use aggregate. jamie > Christine wrote: > I have been asked to set up a database for a questionnaire that has > already been written.

I was going to set it up in epidata but my problem is how to deal witha question that asks people to rank options. The question gives a list of topics and asks the person filling in the questionnaire to rank them from 1-10 in order of importance. I suggest to do the following: For each question (say 25 different themes) enter the priority the person gave to that issue. setup the qes: v1 item1 ..... ## v2 item2 ..... ## etc v25 text for item 25 ## in chk make the defaultvalue 0: before file DEFAULTVALUE v1-v25 0 end Then in analysis after entering the data: (say you had the 25 variables) read response aggregate /sum="v1,v2,v3,v4,v5" aggregate /sum="v6,v7,v8,v9,v10" etc * the tables will show the sum of the variables, that is the overall ranking sum. example read bromar // example data set for epidata aggregate /sum="dectime,km,age" which gives the output: N Ndectime SUMdecti1 Nkm SUMkm Nage SUMage 4027 3556 13913.85 3620 381084.00 3786 153740 telling us: 4027 observations in all of these 3556 contributed to dectime, 3620 to km and 3786 to age variables. Sum of the three being 13913.85, 381084.00 and 153740 Obviously here the sum makes no sense, but in your case the sum of the ranking would reflect all of the variables and the responses. regards Jens Lauritsen EpiData Association ps. I tried to locate the user sending spam to the list today/yesterday and may effectively have deleted this person from the list (if not we will see more of the same spam) - terribly annoying.

Ranked variable questions

by epidata-list＠lists.umanitoba.ca

Hello everyone I have been asked to set up a database for a questionnaire that has already been written. I was going to set it up in epidata but my problem is how to deal with a question that asks people to rank options. The question gives a list of topics and asks the person filling in the questionnaire to rank them from 1-10 in order of importance. (It is for a city council and they want to know what young people are most concernred about so the choices are crime, employment, environment etc). I thought in the qes I could just make a variable for each topic and enter the number the respondent puts beside it, but I don't know how to then analyse the answers, so I can find out what the top 10 issues are overall. If anyone has done this before and can offer a suggestion I would be grateful thanks Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 -- The information contained in this email and any attachments is confidential and may be legally privileged.

Just add "IMIF" in each select group: (here shown with one group): TYPE "\LTABLE SHOWING ILLNESS IN THE SES CLASS 2" SELECT SES=2 count /q * in the next line we use a resultvariable called $count: * resultvariables are shown with the command "result" imif $count > 0 then TABLES SEX ILLNESS else type "No observations" endif Select Regards Jens Lauritsen EpiData Association

Incomplete execution of PGM

by epidata-list＠lists.umanitoba.ca

Dear All, I am bringing to your kind attention one more and last problem. Hopefully this will be looked into before the release of ver 2 of Epidata Analysis. I have a sample database of distribution of illness according to the socio- economic status in the population. The socio- economic status is divided into 1,2 and 3 classes. The sample SES.pgm is listed below.. *SES.PGM CLS CLOSE SET ECHO=OFF READ "D:\EPIDATA\SES\SES.REC" TYPE "\LTABLE SHOWING ILLNESS IN THE SES CLASS 1" SELECT SES=1 TABLES SEX ILLNESS SELECT TYPE "\LTABLE SHOWING ILLNESS IN THE SES CLASS 2" SELECT SES=2 TABLES SEX ILLNESS SELECT TYPE "\LTABLE SHOWING ILLNESS IN THE SES CLASS 3" SELECT SES=3 TABLES SEX ILLNESS SELECT *END OF PGM When I run the PGM, following output is generated. TABLES SHOWING ILLNESS IN THE SES CLASS 1 Sex Illness F M Total N 2 1 3 Y 0 3 3 Total 2 4 6 TABLES SHOWING ILLNESS IN THE SES CLASS 2 No data! Operation aborted Since there is no data in the socio-economic class 2, the PGM aborts the operation. The rest of the PGM is not processed. I am attaching a sample SES.ZIP containing the necessary qes, chk and rec files. The latest test ver 2 (build 112b) of Epi Analysis was used. If this feature is looked into, large PGMs can be run without sny break. Is there any solution of this problem? Dr. Shavinder Singh

reuse labels in several files

It seems that EpiData creates > a block in the .CHK file that applies to one variable only. Is there a > way to apply the same checks and labels to several variables at the same > time? > Technique 1: Common label definitions in EpiData.LBL. When you start EpiData Entry there is a default label collection. If you often use the same labels then edit the file EpiData.lbl which you will find in the same folder as the EpiData Enter system (epidata.exe) installed. Then for a given new file create the rec file and in the Enter system use "Add/revise" to add checks to the file. a Go to the first of the variables which should have a given label b. Choose from the list of your predefined labels contained in "Epidata.lbl" and read into the definition box. c. Now switch back to the field in question (F6 goes from the definition box to the field and vice versa). d. Press Ctrl+C e. Move the cursor to each of the other fields and press Ctrl+V and the definition is copied. It takes very short time. If you are thing instead of missing values etc. look in the help file: MISSINGVALUE Missing value has three syntaxes: MISSINGVALUE x [y [z]] which can be used in fieldblocks, and MISSINGVALUE ALL x [y [z]] which can be used in BEFORE FILE blocks, and MISSINGVALUE field1-field5, field6 …. x [y [z]] which can be used in BEFORE FILE blocks You see that in this case you can use syntax similar to Stata x-y . But for labels the trick above is the only possible. Technique 2: automatic revise of a larger file for subsets: The other technique to use is to create a common (large) file with all relevant questions, properly labelled. Then for a given substudy do: 1. create copies of the common large rec file and associated chk file 2. create copy of qes file 3. edit the qes file and delete sections not currently needed. 4. choose the rec file for entering data. Enter will "see" that the qes file has a more recent date and time and will suggest to adapt the structure to the qes file. Say yes to this and you will see that a number of no longer used variables will be removed including the chk for those. In terms of the analysis programme the issue is somewhat different, but I read the question as being relevant for entry. regards Jens Lauritsen EpiData Association
