Just condition on -e(sample)-. I am not quite sure what "table the results"
is supposed to mean, though.

Betreff: st: Return results only from observations used in estimated model

Hi:

Suppose I run a model using logistic on a data set with 150 observations:

logistic y x z q r

Now, suppose that because of listwise, the number of observations in the 
logistic model are 120.

How would I table the results (using say only variable x and z) based 
ONLY on the data from the logistic model (i.e., the listwise sample) and 
not the whole sample ?

Thanks in advance,
John.
