An analytical p-value combination method using the Cauchy distribution

Description

The CCT function takes in a numeric vector of p-values, a numeric vector of non-negative weights, and return the aggregated p-value using Cauchy method.

Usage

CCT(pvals, weights = NULL)

Arguments

pvals	a numeric vector of p-values, where each of the element is between 0 to 1, to be combined.
weights	a numeric vector of non-negative weights. If NULL, the equal weights are assumed (default = NULL).

Value

The aggregated p-value combining p-values from the vector pvals.
