Hello, I want to know how to perform stepwise elimination of variables to svyglm
If that's actually what you want to do (which as Frank points out, it probably isn't), you'll have to do it by hand. The function step() uses AIC. As far as I know, no-one has yet constructed valid analogues of AIC,BIC,CIC, ... under complex sampling (Alastair Scott and I are looking into it), so p-values are the only option, making the process even less useful. - thomas
