Re: st: Svy subsamples
Richard, without more details I cannot be certain. However, if her
purpose is analytic, namely to study relationships, do hypothesis
tests, compute regressions, I'd say go ahead and subset the data. In
fact, I'd suggest that you ignore the study weights, especially if
they were post-stratified, but that is a different issue.

I know that when using the svy: prefix, you should use the subpop
option when analyzing subsamples, rather than using if or dropping
cases. However, I have a student who has this monstrous data set
and she only wants to analyze a small subset of it. I'm afraid
that if she has to keep all these unused cases in her file, her not-
so-powerful computer is going to have problems.
Is there a legit way to extract only the cases you want? Is it all
that horrible if you extract cases rather than use subpop?
Thanks for any info. And Happy Thanksgiving to all those who
celebrate it.
