Hi all, I am wondering if the survey package has the capability to describe a multistage survey with PPS clusters. Speficially I have a national survey that is intially stratified by region, then by PPS cluster by locality. I'm not sure if this needs to be done with an FPC statement or if I need to define the conditional probabilities of selection for the clusters. Any insight would be appreciated, Thanks, david rae [[alternative HTML version deleted]]
