- b = consistent under Ho and Ha; obtained from xsmle
- B = inconsistent under Ha, efficient under Ho; obtained from xsmle
- Test: Ho: difference in coefficients not systematic
- chi2(8) = (b-B)'[(V_b-V_B)^(-1)](b-B)
- = -16.71 chi2<0 ==> model fitted on these
- data fails to meet the asymptotic
- assumptions of the Hausman test;
- see suest for a generalized test
