WebIn this article, we provide a new perspective to exploit the full potential of quadratic form statistics and maximum form statistics for testing high-dimensional covariance matrices. We propose a scale-invariant power-enhanced test based on Fisher’s method to combine the p-values of quadratic form statistics and maximum form statistics. After ...

"WebFisher’s combined probability test (Fisher, 1932) uses the P-values from k independent tests to calculate a test statistic v2 F ¼ 2 P k i¼1 ln½P i. If all of the null hypotheses of the k tests are true, then this v2 F will have a v 2 distribution with 2k degrees of freedom.
