I am sorry for sending letters not satisfying your request. This time the attached file is resized only 4k. Hope it works! My problem: In my project there are a series of y/n variables (0: no 1: yes 9:unkown) with default value 0. When I enter default 0 for about 40 times the EpiData goes funny. all qes,chk,rec files are in the attached. The error message after entering 40 of 0 for y/n variable: Access violation at address 00000000. Read of address 00000000. Many thanks and best wishes! hshxue(a)yahoo.com.cn 11:45 2013/4/26

Means

by epidata-list＠lists.umanitoba.ca

Hi, everyone I would like to compare mean values between two groups in Epidata analysis. After did analysis, I saw the result: p-values of Bartlet's test <0.05, so I need p-value of Kruskal Wallid; however, I didn't see this value. How to show this p-values of Kruskal-Wallid. I really hope everyone help me to solve this problem. Many thanks.

Release 1.3.1.2 of EpiData Entry and EpiData Manager available for testing

by epidata-list＠lists.umanitoba.ca

Dear All EpiData Manager: Release date for *1.3.1.2* was: 05.Apr 2013 Release date for *1.3.1.2* was: 05.Apr 2013 From http://epidata.dk/testing.php Before release of 1.3.1.2 we still need to fix some minor issues, such as content of reports and possibly addition of a "bug reporting tool", but apart from that only bugs identified will be fixed before release as production version. The current production version on main download page needs replacement as soon as possible. Since last test release in mid March the following has been fixed: EntryClient: * Question og Headings sometimes disappeared during entry. Manager: * Fixed bug in "Count By ID" (bug was: list index out of bounds) * Added checks to drag/drop (design mover) such that controls cannot be dragged outside of valid area. Including pasting and alignment with fixed distance. - on non-linux this should display a No-drop mouse cursor. (Linux is not working yet.) * Other identified bugs and minor issues fixed, e.g. importing .epx files would crash if many headings existed on main section Please continue to test and report Torsten Christiansen Jens Lauritsen EpiData Association

(no subject)

by epidata-list＠lists.umanitoba.ca

Hi, I'm changing my database from SPSS to EpiData. IIt's a follow-up database, with almost 1050 subjects, and three different time points (baseline, 1fst and 3rd months). In total, I have 703 variables. I wonder if you can help me with which choice should I take to collect and merge this kind of data? Is it better to create only one database (including all time points), or should I have to create three databases - one for each time point? If I create 3 databases, how can I merge it? Ex: case n. 999 - merge baseline data with 1fst month, and with the 3rd month... Can you inform where I can find exemples? Thanks in advance. Carlos
