Just found out that it is not possible with robust standard errors, but doable
with ordinary SE. Why?

Hi all,
I was running IV regressions in a loop using gretl 2024d in windows 10, and saw
that while it calculates first stage F, it does not do the same with Cragg -
Donald statistic. Is there a reason for it?
How can we calculate it the Cragg - Donald with e.g. matrices? Is there a
simple formula to do it?
Best,
Andreas
