st: Re: Questions on weights on regressions

["Michael Blasnik" <michael.blasnik@verizon.net>]

I think I can answer your first question -- you did not reproduce the 
aweight results because you also need to multiply the constant by the weight 
(create a new variable and then use the nocons option).
