st: Using weights and robust with ivprob (Amemiya's gls)

["Conway, Karen" <ksconway@cisunix.unh.edu>]

Hi all,

I am happy to discover ivprob, which estimates Amemiya's Generalized
Least Squares estimator, but am disappointed to find that it does not
support sample weights nor the robust option.  Have any of you found a
way of implementing these options?  Thanks so much for any help you can
give.
