Description

Ho: |μ_2-μ_1| ≥ margin

Ha: |μ_2-μ_1| < margin

Usage

WilliamsDesign.Equivalence(alpha, beta, sigma, sequence, delta, margin)

Arguments

alpha	significance level
beta	power = 1-beta
sigma	standard deviation in crossover design
sequence	total sequence number
delta	the superiority or non-inferiority margin
margin	margin=μ_{1}-μ_{2}
