st: weighting in bootstrapping
I have a stratified sample and have computed a statistic within each
stratum. It is a ratio of some quantities and there is interest to see if
the ratio is 1. I want to combine these estimates over the strata to get a
population wide estimate and a test to see if the combined ratio is 1. The
bsample command allows weights, but I am interested in determining if it is
permissible to issue the command
bootstrap "statacommand y [w=freq]" _b[outvar],reps(1000) bca etc.
That is, are weights OK in the bootstrapped command? And do they operate as
if I had a total of N=sum(stratum frequencies) observations, or do they
sample the entire stratum?
I don't have the data in hand yet, so I can't try it out and find out
I need some help with bs (my friends will, of course, immediately
