Hello List,
I did read this post
http://www.stata.com/statalist/archive/2008-07/msg00820.html
I updated stata.
I know I don't have missing data because I imputed values.
When I ran one of my subpop models I got the correct number of
observations. However when I run models on the smaller
sub populations I get the missing observations.
What could still be causing this problem?
Thanks,
Melissa
