V1.1 of EpiData Analysis ready (?)
by epidata-list＠lists.umanitoba.ca 31 Dec '05

31 Dec '05

Unless someone finds serious bugs in the testversion of EpiData Analysis v1.1 build 61 available from: the testing page: Http://www.epidata.dk/testing.php will be released for general usage about one week from today. Translation procedures have started and a preliminary partial installation procedure in Spanish can be tested. Many aspects are updated and enhanced. See: Http://www.epidata.dk/testing.php for a complete list. The major issue is a new focused help system, an aggregation (collapse) command and extensions such as a cumulative column in frequency tables. Work on revision of the stratified table analysis module will be made within the first quarter of 2006, in particular due to a recent donation from Health Canada and the Statistical Process Charts will be extended due to the collaboration with Gruk Norway. Regards and happy new-year to all Jens Lauritsen EpiData Association

New build of EpiData Entry and advancements on Analysis and a new help window
by epidata-list＠lists.umanitoba.ca 17 Dec '05

17 Dec '05

The reported problems of EpiData Entry when verifying double entry has been solved. The problem was that when the file to compare with was missing, then a mysterious error message was given. The principle has now been changed such that if the comparison file is not existing, then the verify procedure stops completely. The path information in the ...dbc file is no longer placed there. Therefore if the user wishes to compare to a first entry file residing in a different folder than where the ...dbl.rec file resides, then manually edit the ....dbc file. Analysis is advancing A lot of work has been put into finding a managable help file structure, which also accomodates translation. If you see on the http://www.epidata.dk/testing.php page, you will see that there is now a partial translation to Spanish and the English version. Some issues of always showing the correct file is still lacking, but is expected to be fixed within a few weeks. The test versions are placed on: http://www.epidata.dk/testing.php The upgraded EpiData Entry (build 18dec2005) is on the http://www.epidata.dk/download.php Version information for entry: http://www.epidata.dk/revision.htm analysis: http://www.epidata.dk/versioninfo.htm Kind regards Jens Lauritsen EpiData Association

RE: [EpiData-list] Date variable
by epidata-list＠lists.umanitoba.ca 15 Dec '05

It's more simple to to it step by step: 1- Your qes file has to contain a variable (string, length = 4. I call it YV1)) to store the year of the date entered in V1. 2- In the chk file, edit checkblock for V1, and add the line: YV1 = year(V1) 3- Then, it is possible to enter the check lines that will calculate the categories: If YV1 = "xxx" then CATEGORY = "xxx" Endif If YV1 = "yyy" then CATEGORY = "yyy" Endif (...) End (assuming there is a variable called Category!) That's it. It's better (although you can do without) to add NOENTER to YV1 checkblock, so that it will be impossible to enter another value by accident.

Howto: Group a date variable by calendar year
by epidata-list＠lists.umanitoba.ca 14 Dec '05

14 Dec '05

* Example pgm file to group a date variable V1 * created by: Jens Lauritsen, EpiData Association set show info=off generate 50 // generate 50 empty observations for testing define v1 <dd/mm/yyyy> define y #### y = 1900 + recnumber // could also be 1900 + _n v1 = dmy(1,7,y) * so now we have a date variable with dates from 1900 to 1950 * three different strategies to group. * Strategy 1: extract year from the date and recode to a string: define y1 #### define ys ________________________ y1 = year(v1) recode y1 to ys by 10 tab ys * Strategy 2: round the number into 10 year groups define y2 #### y2 = year(v1) y2 = trunc(y2/10)*10 // creates groups by 10 years tab y2 * If you use 5 instead of 10 you get 5 year groups * y2 = trunc(y2/5)*5 // creates groups by 5 years * strategy 3: split on specific dates: define y3 # let y3 = 0 if (v1 < dmy(1,10,1930) ) then y3 = 1 if (v1 >= dmy(1,10,1930)) and (v1 < dmy(1,10,1939) ) then y3 = 2 if (v1 >= dmy(1,10,1939)) and (v1 < dmy(1,10,1960) ) then y3 = 3 tab y3 * run the above to get the tabulations. ---------------------------------------------------------------------------------- Output: E.g. for strategy 1: No. % Cum % 1900 - 1909 9 18.00 18.00 1910 - 1919 10 20.00 38.00 1920 - 1929 10 20.00 58.00 1930 - 1939 10 20.00 78.00 1940 - 1949 10 20.00 98.00 1950 - 1959 1 2.00 100.00 Total 50 100% * strategy 2: No. % Cum % 1900 9 18.00 18.00 1910 10 20.00 38.00 1920 10 20.00 58.00 1930 10 20.00 78.00 1940 10 20.00 98.00 1950 1 2.00 100.00 Total 50 100% * strategy 3 No. % Cum % 1 30 60.00 60.00 2 9 18.00 78.00 3 11 22.00 100.00 Total 50 100% ---------------------------------------------------------------------------------- Regards Jens Lauritsen EpiData Association

Double Entry Verification Mode Error, not virus
by epidata-list＠lists.umanitoba.ca 13 Dec '05

13 Dec '05

Hi, When I opened the T3_dbl.REC file for double entry, the system suggested that "DOUBLE ENTRY VERIFICATION MODE Error". I could open the T3_dbl.REC file, but I couldn't verify the entry. Why? How to solve it? There are some Chinese characters in the REC file.

Color of files during data entry and backup as check file command
by epidata-list＠lists.umanitoba.ca 12 Dec '05

12 Dec '05

In the help file users can find information on this: color data black yellow aqua color background white But not further information on how to use these check file commands. One example is: BEFORE FILE color data black yellow aqua color background white end Which will give yellow fields and aqua current entry fields. The background will be white and the colour of texts black. Backup as check file command The backup command documentation is incorrect in the help file. The help file says: AFTER FILE BACKUP F:\backup\distinationdirectory ZIP myzipfile.zip [DATE] END This should be: (to create a zip file with the date appended to the zip file name) AFTER FILE BACKUP F:\backup\distinationdirectory ZIP myzipfile [DATE] END It is always good practice to search the help file for a given word and if the examples are insufficient - then suggest to the list how it could be formulated. If users are not using the help system and this is due to faulty help system, then criticise the help system. But sometimes it appears that questions are asked without the user spending time on: 1. Looking in the help system 2. Searching old messages in the epidata-list on the topic 3. Looking in the further documentation supplied at the web page. http://www.epidata.dk/documentation.php We are now experimenting with solutions to translate analysis and create focused help. Users knowing of funding resources for translation please contact me at: info"at"epidata.dk (replace "at" with @) Best Regards Jens Lauritsen EpiData Association

RE: [EpiData-list] "date" fields
by epidata-list＠lists.umanitoba.ca 12 Dec '05

12 Dec '05

I don't think it is possible to modify the way EpiData 'understands' dates. Nevertheless, you cas add a check that refuses the date when it doesn't verify a certain condition: For example, if the date has to be at least 10 days before the date of entry, you will aff the following checkblock to the date field: DATE1 If DATE1 > today - 10 then Help "DATE1 has to be at least 10 days before today" goto DATE1 Clear DATE1 ENDIF END Line 1 (Help...) will display an error message each time the error condition is met. Line 2 & 3 (Goto / clear) will, as soon as the error message is akcnowledged, return to the field and erase what was previously entered, until a valid entry is entered (or nothing). ______________________________________________ Gilles DELMAS Institut de Veille Sanitaire Dept.
