RE: st: Test of equality of the coefficients between two samplesendogeneity and IVREG2
I am using IVREG2 with gmm option to estimate the coefficient of a dichotomous endogenous variable (migrated=1 or 0). I apply the model to two samples. I would like to test for the equality of the two coefficients between the two samples. Is there a particular test in IVREG2 (with gmm option) that is equivalent to OLS Chew test?
Thank you in advance
