                           b = consistent under Ho and Ha; obtained from xtreg

            B = inconsistent under Ha, efficient under Ho; obtained from xtreg

 

    Test:  Ho:  difference in coefficients not systematic

 

                  chi2(4) = (b-B)'[(V_b-V_B)^(-1)](b-B)

                          =  -109.73    chi2<0 ==> model fitted on these

                                        data fails to meet the asymptotic

                                        assumptions of the Hausman test;
