All
I am trying to write my first Stata program and was wondering if someone could go through it and tell me if it's correct, how I should refer to id and what rclass means (just copied that).
Another thing, I compiled it once and then wanted to recompile it. How do I do that?
Thanks, Dirk

sort id
by id: egen count=count(id)
sum count
local max=r(max)
keep if count==max
}
end
