摘要
In this article, we propose a new nonparametric test for linear hypothesis on regression parameter in linear models with high dimensional explanatory variable, which is a fundamental important problem in the statistical theory and applications. We systematically study the theoretical properties under both the null hypothesis and a local alternative hypothesis, which is the sum of a normal distribution and a mixed chi-square distribution. We conduct a wild bootstrap simulation method based on U centering that could improve the accuracy, and further provide insights into its feasibility. The merit of our method is demonstrated by both simulation studies and real examples.
