Two Sample Crossover Design Test for Equivalence

Description

Ho: |margin| \ge delta Ha: |margin| < delta

This test is whether the test drug is equivalent to the control in average if the null hypothesis is rejected at significant level alpha

Usage

TwoSampleCrossOver.Equivalence(alpha, beta, sigma, delta, margin)

Arguments

alpha	significance level
beta	power = 1-beta
sigma	standard deviation in crossover design
delta	the superiority or non-inferiority margin
margin	margin=\mu_2-\mu_1 the true mean difference between a test mu2 and a control mu1
