A simple approximation for the distribution of the weighted combination of non-independent or independent probabilities

Abstract

This paper presents a simple approximation for the distribution of the weighted Fisher's statistic , which is suitable for use when P1,P2,...,Pk are non-independent or independent tail-area probabilities arising from k continuous distributions, and w1,w2,...,wk are constants.Combination of significance tests Fisher's method of combining probabilities Weighted combination
