Analysis V2 - Congratulations

by epidata-list＠lists.umanitoba.ca

Although there are a few minor bugs, these will usually be very obvious and only in the unusual situation. My quick testing on favourite troublesome data sets shows this is a great release. If you know anyone working on outbreak investigations who has not seen Analysis, do them a favour and show them how to do the following on the OSWEGO.REC data: tab ill cakes vanilla chocolate /oa /ex gen i onset=(onsettime div 100) + iif(onsetdate = "04/19",24,0) epicurve onset ill You will make someone very happy, I'm sure. Many of us working in the field have been waiting for something as simple as this (I have been waiting over 25 years). Sure, you could almost do this in EPI6, but only with a lot of advanced knowledge - and forget the exact test except as table by table. Many thanks to Jens & team!!

Re: EpiData Analysis - first "silent" non-test release

by epidata-list＠lists.umanitoba.ca

The bugs in Chi Square values in stratified analysis of 2x2 tables and the correlation command error reported today has been solved. Therefore a first version v2.0 for analysis placed on the general download page. The work continues solving minor problems only affecting special situations, such as percentiles with small numbers of observations (n=10-25) or final adaptation of all help documents to the new options. Only the general help file has at this point been uploaded. When all of these points have been settled a general announcement will be made. This is expected to take 1-2 weeks. Thanks to many users for testing and commenting. regards Jens Lauritsen EpiData Association

CORRELATE command

by epidata-list＠lists.umanitoba.ca

Dear Jens, After years of hard work you have brought Epi Analysis to the current status. There are almost all the features of EPI6 and much more. Apart from the pending issues you have outlined, I wanted to draw your kind attention to CORRELATE command (build 126). According to the HELP file, correlate var1 var2 [var3 ...], it should work.. When I run this command, the following happens; table design=box . CORRELATE V1 V2 Invalid floating point operation Probably some thing is wrong in the syntax I am attaching a small sample corr.rec file. Please help. Waiting for the release of this marvelous software. With regards, Dr. Shavinder Singh

EpiData Analysis - status release candidate

by epidata-list＠lists.umanitoba.ca

Three aspects needs clarification and further exploration : 1 Chi Square values in stratified analysis of 2x2 tables 2 Saving datafiles with "Epi6 naming convention". Only "First Word" works completely. 3 Percentiles have problems with small numbers of observations Except for these three problem areas I think all major issues have now been solved. The table command syntax has been simplified to: tables ........ (default) will do stratified analysis or a n*k table. tables ....... /oa will create a condensed outbreak table with attack rates and rr tables ........ /cc a condensed table with odds ratios tables ....... /fv will do a "first against all other variables", but currently is limited to 2x2 tables It is my intention to release current as a "silent starter" for v2. By silent I mean without a lot of news due to the limitations mentioned above. A warning is given when the analysis commands (tables, describe, stattable) affected by the problems are used. I expect the problems to be solved within about a week or two at most. The reason for the "silent release" is that some courses are due, which do not use these commands. What could change my decision of release as is would be strong disagreement from users on this list. Please discuss, but if no major concerns show up, the release will happen tomorrow. regards Jens Lauritsen EpiData Association
