I have the final sample weight (expansion factor) from a socieconomic survey. I don't know the exact design used in the study ( (probably is a stratified two-stage design). To illustrate my problem I will use the next dataset which have a sample weight (but the design is not specified) and incorporate the design with svydesign and create some bootstrap replicates in order to be able to produce estimations. Is that correct?: load(url("http://knutur.at/wsmt/R/RData/small.RData")) library(survey) small.w <- svydesign(ids = ~1, data = small, weights = small$weight) design<-as.svrepdesign(small.w,type="bootstrap", replicates=100) Cordialmente Jose F.

hi, probably not.. if your survey dataset has a complex design (like clusters/strata), you need to include them in the `svydesign` call. coercing an incorrect survey design into a replicate-weighted design will not fix the problem of failing to account for the sampling strategy On Mon, Apr 4, 2016 at 12:01 AM, Jos?

I would say **Fortune Nomination!** -- except that this may be a bit too technical and statistical. But it's well said, nevertheless. Thanks. -- Bert> > On Mon, Apr 4, 2016 at 12:01 AM, Jos?
