Re: st: robust/clustered standard errors with ivprob/divprob
I'll venture a very incomplete reply...
If no one has responded, I think you will probably have to take
ivprob and change the code yourself.
And while you're at it, you might want to change the code a bit. I
was just looking at it, and noticed that a loop starting around line
30 generates fitted values and residuals, but they are created as
floats instead of doubles. I wonder if this could generate numerical
inaccuracy problems; doubles would be safer.
