方差加权KS统计量的渐近分布

On the Asymptotic Distribution of Variance Weighted KS Statistics

Timothy B. Armstrong

摘要:

本文导出了协变量为一维的条件矩不等式模型的方差加权Kolmogorov-Smirnov统计量的渐近分布。渐近分布仅通过单个随机变量的方差依赖于数据生成过程,从而导致可以通过分析计算的临界值。通过Armstrong(2011 b)的论证,由此产生的测试在广泛的设置类别中实现了可用方法中局部替代方案的最佳极大极小率。

英文摘要:

This paper derives the asymptotic distribution of variance weighted Kolmogorov-Smirnov statistics for conditional moment inequality models for the case of a one dimensional covariate. The asymptotic distribution depends on the data generating process only through the variance of a single random variable, leading to critical values that can be calculated analytically. By arguments in Armstrong (2011b), the resulting tests achieve the best minimax rate for local alternatives out of available approaches in a broad class of settings.
