One Sample Mean Test for Equivalence

Description

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

The test is concluded to be equivalent to a gold standard on average if the null hypothesis is rejected at significance level alpha

Usage

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

Arguments

alpha	significance level
beta	power = 1-beta
sigma	standard deviation
margin	margin=\bar{x}-\mu_0 the difference between the true mean response of a test \bar{x} and a reference value \mu_0
delta	the superiority or non-inferiority margin
