Description

sample size-weighted Fisher's method

Usage

wFisher(p, weight = NULL, is.onetail = TRUE, eff.sign)

Arguments

p

A numeric vector of p-values

weight

A numeric vector of weight or sample size for each experiment

is.onetail

Logical. If set TRUE, p-values are combined without considering the direction of effects, and vice versa. Default: TRUE.

eff.sign

A vector of signs of effect sizes. It works when is.onetail = FALSE

Value

p : Combined p-value

overall.eff.direction : The direction of combined effects.
