Sargan test of overid. restrictions: chi2(16)   = 158.74  Prob > chi2 =  0.000

  (Not robust, but not weakened by many instruments.)

Hansen test of overid. restrictions: chi2(16)   =  27.76  Prob > chi2 =  0.034

  (Robust, but weakened by many instruments.)

Difference-in-Hansen tests of exogeneity of instrument subsets:
