Hello,
I am running linear regression analyses using STATA, in several East African countries, but each regression analysis is run separately for each country. I am using the child file, with the appropriate weights (svyset v021 [pweight = sampwt], strata(v022) vce(linearized) singleunit(scaled)) to run my regression analyses in STATA.

I am trying to determine that if I use a country's region as a predictor variable, whether it is incorrect to use an administrative unit (such as province or DHS designated region; v024) different than one one used in the stratification of the sample design(v022 or v023). I still use the svyset command to run my regression.

Thank you,
Karoun

Following is a response from Senior DHS Stata Specialist, Tom Pullum:

It is ok to use a regional categorization that differs from the stratification in the survey design.
