Whether your data require simple weighted adjustment because of differential sampling rates or you have data from a complex multistage survey, Stata’s survey features can provide you with correct standard errors and confidence intervals for your inferences. All you need to do is specify the relevant characteristics of your sampling design, including sampling weights (including weights at multiple stages), clustering (at one, two, or more stages), stratification, and poststratificaion. After that, most of Stata’s estimation commands can adjust their estimates to correct for your sampling design.
