摘要
基于 PP技术、Bootstrap方法和数论方法 ,对于 k个总体协方差矩阵相等的检验 ,给出了 PP型检验统计量 ,并讨论了它的渐近分布和 Bootstrap逼近 ,最后给出了一些实际模拟结果 .
In the paper by using Projection Pursuit(PP) technique,Bootstrap method and number- theoretic method,the test statistics of PP type for testing the equality of covariance matrices of k- population is constructed. Furthermore,the asymptotic distribution and the Bootstrap approximation of the test statistics are considered.Several simulation experiments are performed.
