On a Test for the Isotropicity of the Variance Tensor

[摘要] If the sample variance tensor be Φ for a normal 2-dimensional vector population (the mean is unspecified), we can test the null hypothesis H0: the population variance tensor is isotropic, by a statistic G, which is equal to_??_. The sampling distribution of G is given by orwhere N means the size of the sample.
