Combine independent studies using the sum of p-values transformed into standard normal variables

Usage

Arguments

x

is an array of independent p-values

Details

Considering a set of m independent significance tests, the resulted p-values are independent and uniformly distributed between 0 and 1 under the null hypothesis. Stouffer's method is similar to Fisher's method (fisherMethod), with the difference is that it uses the sum of p-values transformed into standard normal variables instead of the log product.

Value
