Dear Statalist;
I am STATA 11 user.
I have sorted my data as -
sort varlist1 (varlist2) (varlist3) (varlist4)
Now I want to perform STATA command: thru_dt[_n+1) - from_dt[_n] by
varlist2 (not varlist1, keeping sort order performed earlier)
with STATA command:
by varlist1 (varlist2): gen x = thru_dt[_n+1) - from_dt[_n]
STATA verifies that data are sorted by varlist 1 varlist2 and performs
command by varlist1.
I will highly appreciate suggestion on "How to perform STATA command
for varlist2 in above situation.
Thanks.
Dilip
