TFisher (version 0.2.1)

Optimal Thresholding Fisher's P-Value Combination Method

Description

We provide the cumulative distribution function (CDF), quantile, and statistical power calculator for a collection of thresholding Fisher's p-value combination methods, including Fisher's p-value combination method, truncated product method and, in particular, soft-thresholding Fisher's p-value combination method which is proven to be optimal in some context of signal detection. The p-value calculator for the omnibus version of these tests are also included. For reference, please see Hong Zhang, Tong Tong, John Landers and Zheyang Wu (2020) "TFisher: A powerful truncation and weighting procedure for combining p-values" .
