具有Berkson测量误差的最小距离回归模型检验

Minimum distance regression model checking with Berkson measurement errors

Hira L. Koul, Weixing Song

摘要:

具有Berkson测量误差的回归模型的失拟检验至今尚未在文献中讨论。为了填补这一空白,我们提出了一类测试的基础上最小化集成平方距离之间的非参数回归函数估计和参数模型拟合。在原假设下证明了这些检验统计量的渐近正态性,并证明了在极小条件下相应的最小距离估计量的渐近正态性。我们还证明了对一类固定的替代品,并获得他们的渐近权力对一类本地替代正交的原假设的建议测试的一致性。即使在没有测量误差的情况下,后面这些结果也是新的。所包括的模拟显示非常理想的有限样本行为的建议的推理程序。

英文摘要:

Lack-of-fit testing of a regression model with Berkson measurement error has not been discussed in the literature to date. To fill this void, we propose a class of tests based on minimized integrated square distances between a nonparametric regression function estimator and the parametric model being fitted. We prove asymptotic normality of these test statistics under the null hypothesis and that of the corresponding minimum distance estimators under minimal conditions on the model being fitted. We also prove consistency of the proposed tests against a class of fixed alternatives and obtain their asymptotic power against a class of local alternatives orthogonal to the null hypothesis. These latter results are new even when there is no measurement error. A simulation that is included shows very desirable finite sample behavior of the proposed inference procedures.
