Dear Statalisters;
 I have a question regarding the over-identification
restriction Tests(Sargan or Hansen test). When using a
DPD estimator I always get these tests' p-values
equals one (chi2=45 and p-val = 1.000); does that cast
any doubt on my estimation results or my model?!
Any suggestion or comments will be highly appreciated.
