大家好,向高手请教,使用xtabond2命令,建立多个差分GMM模型,结果如下: 是否说明hansen和Sargan可以?。
Sargan test of overid. restrictions: chi2(620) = 531.97 Prob > chi2 = 0.995
(Not robust, but not weakened by many instruments.)
Hansen test of overid. restrictions: chi2(620) = 14.57 Prob > chi2 = 1.000
(Robust, but weakened by many instruments.)
