研究了非参数回归模型中回归函数单调性的检验问题。我们引入测试统计量,是一个特定的自然U-过程的泛函。利用强逼近方法和高斯过程的极值理论研究了这些检验统计量的极限分布。我们表明,测试是一致的,对一般的替代品。
We consider the problem of testing monotonicity of the regression function in a nonparametric regression model. We introduce test statistics that are functionals of a certain natural U-process. We study the limiting distribution of these test statistics through strong approximation methods and the extreme value theory for Gaussian processes. We show that the tests are consistent against general alternatives.
