OneSampleProportion.NIS: One sample proportion test for Non-inferiority/Superiority

In TrialSize: R Functions for Chapter 3,4,6,7,9,10,11,12,14,15 of Sample Size Calculation in Clinical Research

One sample proportion test for Non-inferiority/Superiority

Description

Ho: p-p0 \le margin

Ha: p-p0 > margin

if margin >0, the rejection of Null Hypothesis indicates the true rate is superior over the reference value p0;

if margin <0, the rejection of the null hypothesis implies the true rate is non-inferior against the reference value p0.

Usage

OneSampleProportion.NIS(alpha, beta, p, delta, differ)

Arguments

alpha	significance level
beta	power = 1-beta
p	the true response rate
delta	delta=p-p0 the difference between the true response rate of a test drug and a reference value p0
differ	the superiority or non-inferiority margin
