<> The weird thing about the solutions in this thread is that they do not conform to Rebecca`s request to get means accounting for survey weights the same way -egen, mean()- does for non-weighted data: as a vector over all observations in the dataset. The easiest solution that I can see is to employ -svy: regress- and -predict-. ************* webuse highschool, clear svyset county [pweight=sampwgt], strata(state) vce(linearized) // use -regress- to get means svy linearized: regress weight sex //see whether adjust matches -mean- results adjust, by(sex) xb se //get predictions predict pred if sex==1, xb predict female if sex==2, xb replace pred=female if pred==. drop female // get ses predict se if sex==1, stdp predict sefemale if sex==2, stdp replace se=sefemale if se==. drop sefemale l sex pred se in 1/10 //compare to -mean- svy: mean weight, over(sex) ************* HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von Kanter, Rebecca Gesendet: Mittwoch, 8. April 2009 02:31 An: statalist@hsphsun2.harvard.edu Betreff: RE: st: Saving svy mean estimates? Joao, Thanks for your response; that helps a bit. But what I'm trying to get at is how to store the e(b) (i.e. mean values) into a variable [the same way as if I did egen newvar=mean(var), without acct for svy design]. Do you or someone else know how to do this? Many thanks, Rebecca ___________________________________________ Rebecca M.
