I need some guidance from someone who is familiar/has some experience with the survey package.
The data that I am using is from the Medical Expenditure Panel Survey (www.meps.ahrq.gov <http://www.meps.ahrq.gov/> ). The STRATA and PSU variables are varstr01 and varpsu01 respectively. When I try to specify them with the svydesign function I get an error message. An excerpt of my session is as follows... library(foreign) > h60 <- read.xport("h:\\meps\\temptransports\\h60.tpt") > names(h60) <- casefold(names(h60)) > names(h60) [1] "dupersid" "sex" "inscov01" "totexp01" "perwt01f" "varstr01" "varpsu01" > library(survey) > meps.design <- svydesign(id=~varpsu01, strata=~varstr01, weight=~perwt01f, data=h60) Error in svydesign(id = ~varpsu01, strata = ~varstr01, weight = ~perwt01f, : Clusters not nested in strata > I'm not sure what is causing this error message or how to get around it (i.e., remedy the problem). Any insight would be much appreciated. Thanks. Marc Marc W.
