Greetings SK,

[This may be a repeat -- first posting didn't seem to get through]

I like to use a little program by Christian Maas to generate data, Random file generator from:
   http://www.chmaas.handshake.de/delphi/freeware/freeware.htm   

The command line version can be run from a BAT file containing a statement such as:
RndFileC.exe /R=50000 /Z=YYYY/MM/DD /N=4 /F=1,@ /C=15 /F=1,, /B /C=1 /S=14 /B /C=1 /S=14 /F=1,@ /Y=1945,2003 data.txt

For example, this generates 50,000 records with the given date format and range, plus other fields. Then import into EpiData.

I prefer to set up the EpiData files, enter a few records, and then export them to a CSV file; then make sure you use the same format to generate the random records to import back into EpiData.

I have use Maas's program to generate 8,000,000 records (but not this number for EpiData; this was data to analyze using gawk in GNU/Linux). The sort program is real nice, too.

Hope this helps,

I wish to populate the fields (15 in total, of various types: boolean, categorical with k values, numeric, and date fields) I have created with say N=5,000 observations. The reason I wish to do this is to show the stakeholders (in this case Hospital Managers and Unit Heads) that one could use simple yet effective data entry and analysis software (like EpiData) to monitor and evaluate hospital-based programs. I wanted them to see EpiData in action with the simulated data--starting with EpiData Entry and then with Analysis.
