Subject | st: about multi-stage stratified sampling designing |
Date | Mon, 26 Apr 2010 17:51:25 +0800 |
Hi! Dear statalisters: Because of research, I am working a database which is multi-stage stratified systematic sampling designing. Specially, it adopted three kinds of multi-stage stratified sampling designing that I couldn’t use the normal STATA command- svyset. And how can I do it? By the way, The database managers suggested that users handle the weight by SUDAAN(statistical software) and they released the examples of result. There was a post-stratification weight so that I tried to use the STATA command-poststrata. Unfortunately the results differed from using SUDAAN. SUDAAN declared the sampling designing(strata, psu) and post-weight and the way of STATA used the post-stratification and post-weight. Could you tell me what the different between them?
