On the Behavior of Conditional Moment Tests in the Presence of Unconsidered Local Alternatives
用渐近局部分析研究条件矩检验对未专门设计的误设来源的敏感性,发现最大似然估计下检验的渐近不敏感性与渐近独立性等价,但极值估计下不成立。
This paper employs asymptotic local analysis in order to examine the sensitivity of individual conditional moment tests to sources of misspecification for which they were not specifically designed. In the context of maximum likelihood estimation, the authors find an exact equivalence between the conditions for asymptotic insensitivity of tests and their asymptotic independence. This equivalence does not hold for models estimated by extremum methods. Examples are given to illustrate the general results.
