dear listers,
i am trying to understand one of the do-files application for stata. one of
the lines read:
qui by study: gen last=_n==_N
my understanding so far: this is quietly, sort according to study, and as a
result, to generate a variable last fulfilling this condition _n==-N.
although i have the output, i would like to know what in general does gen
last=_n==_N do?
thank you,
bw
