Re: Number of variables not missing
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.
