...have a few questions: 1 - When the variable 'cluster' is introduced, then only clusters will be resampled (with replacement)? 2 - I can implement 'two-stage' bootstrap in STATA by running bootstrap sampling on top of the bootstrap command. Example: bootsrap cost, cluster(group): bsampling cost treat This means that in the 1st stage I resample clusters (with replacement) and then resample individuals within those clusters. I wonder whether we could do a similar procedure in R, i.e. if it is sensible to do something like: f<-boot(cost~treat) mod<-bootcov(f, cluster, B=1000...
