"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

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

new page every table for printing

>I am trying to print off a number of tables that I have generated. >Preferably one per page and have not been able to accomplish this. Apart from the suggestion by GIlles Delmas you should look at style sheets with EpiData Analysis. See "page-break-before" in the definitions: http://www.w3.org/TR/REC-CSS2/page.html And experiment a bit. Let us all know how you manage. We can then put the style sheet code for general usage in analysis as a "how to ...." regards Jens Lauritsen EpiData Association ps. Regarding the append question. Just try to see how many records are possible. I tried one append ending with 1 million records (10^6) with no problems.

RE: [EpiData-list] Printing Tables

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.

by epidata-list＠lists.umanitoba.ca 11 Sep '05

Thank you and this is good to know. a coupe of questions, please. 1. this suggest the limit to the number of files to be appeneded is realted to machine memory? 2. this is the solution to the "lack" of ability to dynamically read multiple files? Would those of you who have used these techniques please let me know what size of the files you have been working with and, any other options you have used. Thank you very much, Kelly -----Original Message----- From: epidata-list(a)lists.umanitoba.ca [mailto:epidata-list@lists.umanitoba.ca] Sent: Fri 9/9/2005 8:14 PM To: epidata-list(a)lists.umanitoba.ca Cc: Subject: [EpiData-list] Appending Dear Eleni: There are two ways to append - one is within EpiData, the other highly efficient within EpiData Analysis.

Hello! Is it possible to export the data labels to Excel file as well? (e.g. to have labels instead of the variables name then, it works for SPSS and Stata, but could not find it for Excel).

Automating Append/Merge
by epidata-list＠lists.umanitoba.ca 08 Sep '05

08 Sep '05

Use EpiC, which you can download from the epidata website. EpiC let's you send commands to EpiData. It's all explained in the documentation. You can set up a sequence of commands in a file and get Windows to run them whenever you want. Jamie Hockin Public Health Agency of Canada 1.
