RE: st: RE: using multinomials as weights in bootstrapping

[Charley Greenwood <Charley.Greenwood@coffey.com>]

Thanks Maarten.

For some reason I had thought the bootstrapping facility in Stata was locked into running specific regression commands, and I didn't realize it would create weights independently, and I couldn't see a random number function for multinomials. It was interesting trying the long way round, but bsample is what I need.

Thanks again.

the -bsample- command with the -weight()- option, see -help bsample-
