Hello,
Thank you for your reply, but I specify my problem:
- Variables in the questionnaire
Var1 ##
Var2 ##
Var3 ##
Var4 ##
Mean4 ##.##
- In CHECK file (or ANALYSIS)
mean4
mean4 = (var1+var2+var3+var4)/4
end
- But sometimes, var2, for example, can fail (blank):
in this case, "mean4" is the sum (Var1 to var4) divided by 3!
- My question is, how to count automatically (CHECK or ANALYSIS)
the number of variables (var1 to var4) not missing?
Thank you for your help.

Dear Bernard,
What do you think about count if [logical statement].
For example: count if km=. will return the number of km that are missing in
the data set. Additionally you can list such list id if km=.
Please let me know if this helps.

Hello,
In EPIDATA ENTRY or ANALYSIS, to calculate an mean, it is easy to calculate
a sum of several variables (the numerator)(even if some are missing), but I
don't know calculate the number of non-missing variables (the denominator)
as the command "NBVAL" in EXCEL. Thank you for helping me.

Hello all,
I am trying to adapt a program written for an earlier version of EpiData to version 2.2.1.171.
The command for the old version was
. stab sex /mean="age" /des="age"
which printed the following columns:
sex, N, Nage, MEAage, MINage, MEDage, MAXage
If I understand things correctly, I should be able to get the same table using the following command in the new version:
. stab age /by=sex /stat="n mean des"
However, I get a "Unknown aggregate function: N" when I try to execute the above command, even though the documentation mentions the parameter:
* n Number of observations
Also, interestingly, if I execute
. stab age /by=sex /mean
I get no error but just the table
Sex | N
----------
M | 490
F | 3537
Instead of the mean.
Are these bugs in EpiData or do I misunderstand the documentation?
Kind regards,
Simon
