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"
