Re: st: different result each time

Wouldn't you need the latter of the cases you mentioned (merge
variables don't uniquely identify observations in both datasets) for
this to happen? I think you'd get the same result if you have
uniqueness in one dataset. I made up a little example. The second
merge produces different results in both runs, while the first merge
produces identical results.
