Hello Phung,

Would this work ? keep only the data for each stratum, and call your do file.
svyset, clear allows to clear the survey variable which I suppose you have specified in your main analysis.do file.

forvalues k = 1 (1) 26 {
	drop if strata~=`k'
	svyset, clear
	do analysis.do
	}

Dear Statalist

I have a database for a complex survey with 26 strata and 100 PSUs. I have
done the analysis using the svy components for the entire database, and now
would like to repeat the same analysis for each of the 26 strata. The
planned analysis is already a do.file. I have not been able to figure out
how run this do.file for each stratum efficiently as I am not a programmer.
I have tried "by", but it does not work with the svymean or do command. Can
someone give me some advice?  I am using stata 7.0.

Gratefully yours,
Phung
