Dear Stata listers,

forgive me for posting such a basic question. I am using Stata 10.1 to
analyze an original stratified three-stage cluster sample survey in
which observation are farmers (individuals) sampled from groups
(pocode) themselves sampled from larger farmer cooperatives (dccode).
isb17 is a dummy variable measured at the individual level. I am
trying to create a variable at the PSUs level (dccode), which is the
proportion of farmers in the cooperative that have  isb17==1.  I am
reluctant to use the collapse command given the survey design.

svyset dccode [pw= pweight], strata (strata) fpc(fpc1) || pocode,
fpc(npos) || _n, fpc(popop)
svy: proportion isb17, over(dccode)

What I am failing to do, is to take the e(b) from ereturn and generate
a variable that represents isb17==1 at the dccode level.
Help would be highly appreciated.

Cheers,
Guy
