## Stouffer's Test

### Description

This function performs a weighted Stouffer's mehtod of combining p-values.

### Usage

    stoufferTest(pvalues, weights)

### Arguments

`pvalues` | A vector of p-values.
`weights` | Optional weights used when combining probabilites. If no weights are given then the p-values are equally weighted.

### Details

For each p-value the inverse standard normal CDF is applied and Z scores are derived. Z-scores are then summed and a new Z score is transformed back to a p-value.

### Value

A numeric p-value that represents the standard normal CDF of the combined Z statistic.

### Note

This function was adapted from the function written on the Fisher's Method wikipedia page.

### Examples

    ## Generate test weights ##
    weights<-runif(10, 1,100)
    weights<-sort(weights)

    ## Generate test p-values##
    pvals<-runif(10,0,1)

    ## run stoufferTest ##
    stoufferTest(pvalues = pvals, weights=1/weights)
