First, always write to SAS-L isntead of to me personally. You ended up in
my spam filters, and it's a miracle I even saw this today.
Second, don't be doing boostraps on complex sampel designs unless you're
fully conversant in the technical details of design-adjusted bootstraps.
not trivial. You cannot use standard bootstrap estimation when the data are
not exchangeable, as in survey sampling.
Third, standard survey sampling estimation techniques are doing things like
Taylor series linearization or jackknifing, os bootstrapping that is like
your bootstrap. It's not worth the effort.
Perhaps if you write back to SAS-L - and not to me personally unless you
to hire me as a consultant - and explain your problem and your data and your
for wanting a bootstrap at all, then someoen here might be able to help you
