If it is NOT satisfactory, then why don't YOU make it satisfactory,
Ricardo Ovaldia?
You are the one who claimed stata's -qreg- standard errors are wrong.
This is a strong claim. Papers have been published on the assumption
that they are right. If you have evidence that they are wrong, you
should provide it. If you have no evidence, it is my opinion that you
should refrain from making such strong statements in a public forum.
You should certainly not demand that other people not affiliated with
statacorp should prove the Stata standard errors to be right.
