st: RE: xtlogit, excluding individuals with few obs

["Nick Cox" <n.j.cox@durham.ac.uk>]

I can't speak for STATA. In Stata this sounds like 

. bysort id : drop if _N < 4

I want to run xtlogit with many explanatory variables, but some individuals have only few observations. Now I need to find a neat way to exclude those which have few obs. In pseudocode this would be 
for id=1 to 10000 
drop rows(id) if numobs(id)<4 
end 
But how do I do this is STATA?
