st: GMM moment errors

[nadir virk <nadirvirk@gmail.com>]

Hi,
Please can someone help me how to retrieve residuals (e) from the
moment conditions in GMM setting! Can one also retrieve the weighting
matrix (optimal weighting implied by the inverse of e'*e by Hansen
(1982))!
will be thankful for kindness!
Regards,
Nader
