关于只有一个变点模型的非参数推断

In this paper,the estimates and tests of the change point in a linear regression model arediscussed with Wilcoxon rank sum statistic when observations are large enough.Furthermore,the testing procedure on line is presented.Besides,a method for testing the change point is pro-posed with different observations before and after the change point.
