q.tpm: Quantile of truncated product method statistic under the null...

In TFisher: Optimal Thresholding Fisher's P-Value Combination Method

Description

Quantile of truncated product method statistic under the null hypothesis.

Usage

q.tpm(p, n, tau1, M = NULL)

Arguments

p	- a scalar left probability that defines the quantile.
n	- dimension parameter, i.e. the number of input p-values.
tau1	- truncation parameter. 0 < tau1 <= 1.
M	- correlation matrix of the input statistics. Default = NULL assumes independence.

Value

Quantile of truncated product method statistic.

Examples

## The 0.05 critical value of TPM statistic when n = 10:
q.tpm(p=.95, n=20, tau1 = 0.05)
M = matrix(0.3,20,20) + diag(1-0.3,20)
q.tpm(p=.95, n=20, tau1 = 0.05, M=M)
