一般区间数据的无边界核光滑拟合优度检验

Boundary-free Kernel-smoothed Goodness-of-fit Tests for Data on General Interval

Rizky Reza Fauzi, Yoshihiko Maesono

摘要:

我们提出了核型平滑Kolmogorov-Smirnov和Cramér-von Mises测试一般区间上的数据,使用双射变换。虽然不像核密度估计那样严格,但直接将朴素核方法用于这些特定测试也会导致边界问题。这主要是因为当在边界点处评估时,朴素核广义函数函数估计器的值仍然大于$0$(或小于$1$)。这种情况会增加测试的误差,尤其是第二类误差。在本文中,我们使用双射变换来消除边界问题。本文的最后部分将给出一些模拟结果,说明估计器和检验的性能。

英文摘要:

We propose kernel-type smoothed Kolmogorov-Smirnov and Cramér-von Mises tests for data on general interval, using bijective transformations. Though not as severe as in the kernel density estimation, utilizing naive kernel method directly to those particular tests will result in boundary problem as well. This happens mostly because the value of the naive kernel distribution function estimator is still larger than $0$ (or less than $1$) when it is evaluated at the boundary points. This situation can increase the errors of the tests especially the second-type error. In this article, we use bijective transformations to eliminate the boundary problem. Some simulation results illustrating the estimator and the tests' performances will be presented in the last part of this article.
