OneSampleMean.Equivalence: 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
