If it is NOT satisfactory, then why don't YOU make it satisfactory,
Ricardo Ovaldia?
I am quite puzzled why you CANNOT contribute but can blame others? I
did NOT accuse anything but just stated my experience.
BTW, I did NOT say that ALL Stata's SEs are hardly correct.

This is NOT satisfactory, Shinkyu Yang, you stated
that Stata's SE are wrong but do not provide any
supporting evidence. This leaves us, who routinely use
-qreg-, wandering if you are correct and Stata is
wrong or what? If Stata is computing incorrect SE, I
and I'm sure Stata, would want to know this.
I think that is a terrible disservice to Stata and
users to state on this list that something is computed
incorrectly without providing adequate evidence.
Best,
Ricardo.
