I've stset my data, and want to find summary statistics by group.
Because I don't want to overcount some observations simply because
they longer survival times, I am having trouble finding appropriate
summary statistics. For instance, I have approximately 5000 groups,
but after stsetting the data, it has grown to roughly 40,000
observations (though still composed of those same 5000 groups). Is
there a way to tell Stata to calculate summary statistics over just
those 5000 groups?
