That would potentially cause a problem with your standard errors since you are trying to examine a subset. Read the portion of the svy commands in the manual that deals with subsets of samples in analysis. C.

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.
