st: Survey Estimation, stata manual, example: multistage.dta
has anyone an explanation why the sampling weights of a two stage sample
(PSU county, SSU class) varies within a class of the stata demonstration file? The variable sampwgt in the
demo data file (multistage.dta) is not constant within county, class. Is this an error in the file, the manual or
do I miss something?
Many thanks for any hint
