Hi all,
I have done 2SLS estimates using different instrumental variables and
now need to do robsutness checks. Do you have any idea about the tests
that I can conduct?
Also, with XTGLS, how do we select which is the appropriate estimation
(i.e. out of independent, correlated, heteroskdastic, ar1, psar1 etc)?
Thank you very much for all of your kind attention.
Cheers
Dinusha
