re: st: Cluster question

.

see http://www.ats.ucla.edu/stat/stata/library/cpsu.htm

This question has come up before, try a search of the archive. I think I remember the answer being somewhat model dependent. For GEE some said you needed much greater than 20 or 30 clusters. But maybe that is a good minimum.
