强大的推断的一个重要问题是在存在受污染的数据的情况下检查不对称水平的稳定性和测试统计的功率。通过允许在“常规线性模型”类别的类别中,允许使用较宽的鲁棒误差度量(称为“鲁棒”)来检查此问题规律性条件,我们得出了鲁棒参数估计器的影响功能,并证明了鲁棒型测试的有效性和效率不对称的稳健性,该测试的不对称水平是稳定的。零假设,而在连续替代方案的邻居中,在污染的分布下,不对称能力足够大,因此贷款支持提议的效用强大的 - 瓦尔德型测试。
An important issue for robust inference is to examine the stability of the asymptotic level and power of the test statistic in the presence of contaminated data. Most existing results are derived in finite-dimensional settings with some particular choices of loss functions. This paper re-examines this issue by allowing for a diverging number of parameters combined with a broader array of robust error measures, called “robust-BD”, for the class of “general linear models”. Under regularity conditions, we derive the influence function of the robust-BD parameter estimator and demonstrate that the robust-BD Wald-type test enjoys the robustness of validity and efficiency asymptotically. Specifically, the asymptotic level of the test is stable under a small amount of contamination of the null hypothesis, whereas the asymptotic power is large enough under a contaminated distribution in a neighborhood of the contiguous alternatives, thus lending supports to the utility of the proposed robust-BD Wald-type test.
