EpiData Analysis v2.0 Build 128 available
by epidata-list＠lists.umanitoba.ca 22 Nov '07

22 Nov '07

I just uploaded v2.0.1.128 on the page: www.epidata.dk/testing.php This build remedies as far as we can test here the problems shown since release of v2.0: - saving data files with automatic naming - odds ratios in stratified tables with more than two strata - memory leaks. Plan for current testversion: 1. Leave on testing.php page for a few days (3-4 days) 2. Move as current release on the general download page. The reason for putting on the test page is that the memory leak cleanout could have introduced problems with menus and screen handling, which cannot be tested here. Memory demand after running many commands could before rise to more than e.g. 200Mb is now down to around 15-20 Mb. Since release of v2.0 the test suite applied has been extended from 1749 tests to 1884 tests. The extension includes aspects such as further sorting and stratified results for a combination of variables and files. Please test as indicated and report here if you find problems Regards Jens Lauritsen EpiData Association

EpiData Entry: export filter
by epidata-list＠lists.umanitoba.ca 15 Nov '07

15 Nov '07

I am hoping someone knows the answer to the following question: I am trying to export a selection of records from an EpiData rec file using version 3.1 to an Excel file, based on a date field. For instance, to select all records earlier than the 14th of November 2007: dategiven < "14/11/2007" in the filter box, but this yields an error (not a boolean expression) and the field dategiven is a <ddmmyyyy> field. I also tried without quotes and using the date function, with and without the day, month, year functions with the same result. I dare say there is a simple way to do it, but I can't see it, so if anyone can help, I'd be most grateful.

In Build 122 the following 3 commands in a pgm-file could be executed correctly. close read "c:\data\tz\test1.rec" append "c:\data\tz\test2.rec" In build 126 and 127 the You get a error "Invalid variable name C:\Data ....." when running the pgm-file. But if You execute each command separately the APPEND command works.as You can se from the following output. . read Loading data C:\Data\TZ\Test1.rec, please wait..

EpiData Analysis - reported problems solved - build 127 uploaded
by epidata-list＠lists.umanitoba.ca 10 Nov '07

10 Nov '07

The reported problems in relation to b126 have all been solved. In addition the following changes have been implemented: dotplot : Now dots are symmetrical for each group command prompt: At initiation the command prompt is empty (was "read" before". For users wishing to get the "read" command without using a mouse the shortest way is by pressing F4 (goto command prompt) followed by "Up-Arrow" (shows the "read" command), followed by "Enter" (open file dialog). documentation: clarified. Still some of the extended help files could have v1.0 description of options etc. The download page now shows build and version next to the page, as well as there is also a zip file available containing the setup file. Thanks for reporting the problems. Part of the problem of the /SD etc discussed was, that the release build and a former test build had the same build number (b126) (by error), such that users could think they were having the same version, but actually did not. regards Jens Lauritsen EpiData Association

RE: Sorting of 2x2 tables (Oswego example discussion)
by epidata-list＠lists.umanitoba.ca 09 Nov '07

09 Nov '07

The problem of the /sd option in relation to tab ill cakes vanilla chocolate /oa /sd /ex versus tab ill cakes vanilla chocolate /oa /ex is related to how boolean variables are sorted. Currently in the version 2.0 released there is a bug in sorting of boolean 2x2 variables. The error will be fixed as soon as possible. For numerical variables coded 1/0 or 2/1 there is no problem. The reason I did not catch the boolean Y/N error is, that the tab command gives correct estimates for boolean as well as numerical variables: tab ill cakes vanilla chocolate /oa /ex But if the user adds the sorting (as was needed earlier) : tab ill cakes vanilla chocolate /oa /ex /sd reveals the bug. The way development is done is that before release a number of tests are made, currently around 1250, e.g. after the mentioned tabulation 24 tests were applied for the tabulation of oswego rr values with different options (but not the /sd) option. The oswego rr test has now been extended to cover this issue as well. (18 more tests). A given test can be like this using result variables: tab ill vanilla rolls /o assert samenum(round($OR*100)/100,22.15) assert samenum(round($ORLL*100)/100,5.22) assert samenum(round($ORUL*100)/100,138.39) assert samenum(round($OR1*100)/100,12.26) assert samenum(round($ORLL1*100)/100,1.76) assert samenum(round($ORUL1*100)/100,150.86) assert samenum(round($OR2*100)/100,38.19) assert samenum(round($ORLL2*100)/100,4.06) assert samenum(round($ORUL2*100)/100,1983.85) assert samenum(round($SumOR*100)/100,20.61) assert samenum(round($SumORLL*100)/100,4.93) assert samenum(round($SumORUL*100)/100,126.46) The "hidden" bug arising by the sort option is a good example of why many tests are needed, but I think also that it shows that even with a number of test releases the policy of "silent release" is appropriate. regards -- Jens Lauritsen Coordinator and initiator of EpiData Project http://www.epidata.dk

They were using Stata and when they saw EPiData Analysis doing the, them a draft version yet, of tables ..... /oa and epicurve. They got completly breath taken I think Jens deserves all our acknowledge Pedro

Analysis V2 - Congratulations
by epidata-list＠lists.umanitoba.ca 08 Nov '07

08 Nov '07

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 05 Nov '07

05 Nov '07

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
