Re: st: quasi-variances in Stata

[Richard Goldstein <richgold@ix.netcom.com>]

I am not familiar with either Firth or Fox (2008) (note that the FAQ 
asks for complete references); nor am I familiar with the term 
"quasi-variances";

Why not just use the test statement after your regression to test 
exactly the comparison you want?
