Abstract

A general method for constructing pseudo-Gaussian tests—reducing to traditional Gaussian tests under Gaussian densities but remaining valid under nonGaussian ones—is proposed. This method provides a solution to several open problems in classical multivariate analysis. One of them is the test of the homogeneity of covariance matrices, an assumption that plays a crucial role in multivariate analysis of variance, under elliptical, and possibly heterokurtic densities with finite fourth-order moments.

构造伪高斯检验的一般方法
提出了一种构造伪高斯检验的一般方法,即在高斯密度下简化为传统的高斯检验,但在非高斯密度下仍然有效。该方法解决了经典多变量分析中的若干开放性问题。其中之一是协方差矩阵的同质性检验,这一假设在椭圆和有限四阶矩的异方差密度下的多变量方差分析中起着至关重要的作用。
