带函数冗余参数的条件推理

Conditional Inference with a Functional Nuisance Parameter

Isaiah Andrews, Anna Mikusheva

摘要:

本文证明了矩条件模型的假设检验问题在没有任何关于辨识的假设的情况下可以看作是一个具有无限维冗余参数的检验问题。我们引入了一个充分统计量这个冗余参数,并提出了条件检验。这些条件检验对于一大类模型和检验统计量具有一致正确的渐近大小。我们应用我们的方法来构建基于准似然比统计的测试,我们表明,这是有效的强识别模型和现有的替代品在两个例子中表现良好。

英文摘要:

This paper shows that the problem of testing hypotheses in moment condition models without any assumptions about identification may be considered as a problem of testing with an infinite-dimensional nuisance parameter. We introduce a sufficient statistic for this nuisance parameter and propose conditional tests. These conditional tests have uniformly correct asymptotic size for a large class of models and test statistics. We apply our approach to construct tests based on quasi-likelihood ratio statistics, which we show are efficient in strongly identified models and perform well relative to existing alternatives in two examples.
