Dear Statalist,
I have survey data collected through multistage cluster sampling with
stratification. I have a question about command of ?svyset.?
For my data, first, the population was stratified and several clusters
were randomly selected for each stratum. After that, different
sampling methods were used for selected clusters. For some clusters,
sub-clusters were selected and then for each sub-cluster, individuals
were randomly selected. But for some cluster, individuals were
selected without selecting sub-clusters. Moreover, some sub-clusters
were stratified and individuals were selected. In short, strata have
different stages and some have within-stratification (like below).
-Stratification ? clusters ? sub-clusters ? sampling
-Stratification ? clusters ? sampling
-Stratification ? clusters ? sub-clusters ? stratification ? sampling
In this case, I think that the command for multistage design like
below cannot be used for my data.
svyset su1 [pw=pwt], fpc(fpc1) ///
|| su2, strata(strata2) fpc(fpc2) || _n, fpc(fpc3)
Instead, I guess I should have the command like...
svyset [pweight=pwt], psu(su1) strata(strata1)...(without fpc)
I would like to know whether this is correct.
Thank you very much for your advice in advance.
Hisako
