To quote -help weight-:

 "iweights have no formal statistical definition; any command that
supports iweights will define exactly how they are treated.  Usually,
they are intended for use by programmers who want to produce a certain
computation."

So you probably don't want to use iweights anyhow.

Hope this helps,
