Pairwise Comparison for Multiple-Sample One-Way ANOVA

Description

Ho: \mu_i is equal to \mu_j Ha: \mu_i is not equal to \mu_j

The test is comparing the means among treatments. There are tau pair comparisons of interested. Adjusted the multiple comparison by Bonferroni method,

Usage

OneWayANOVA.pairwise(alpha, beta, tau, sigma, margin)

Arguments

alpha	significance level
beta	power = 1-beta
tau	there are tau pair comparisons
sigma	standard deviation
margin	margin=\mu_i-\mu_j the difference between the true mean response of group i \mu_i and group j \mu_j
