Description

Given a set of p-values and a test level, returns vector of test results for each hypothesis.

Usage

hommel.test(p, alpha=0.05)

Arguments

p numeric vector of p-values
alpha numeric value, desired significance level

Details

This function implements the multiple testing procedure of Hommel (1988). Hommel's method is also implemented as an adjusted p-value method in the function p.adjust but the accept/reject approach used here is faster.
