Hi,
I need to run identical regressions for different subsamples of my data
set. I have one variable that defines the different subsamples and I
would like to use this variable together with the "by" command. My
problem is that my regressions contain several command.
My regressions, together with my "post estimation" commands, look like
probit yes lnbid lninc if bid<=income
wtpcikr lnbid lninc if bid<=income, mym(mean1) expo
matrix b=e(b)
matrix beta=b/-b[1,1]
matrix v=e(V)/(b[1,1]^2)
ereturn post beta v, noclear
ereturn display
scalar sigma=1/-b[1,1]
display sigma
Using my variable that defines the different subsamples, I would like to
run the string of commands above for each subsample. Is this possible
using the "by" command?
Thank you
Henrik
