Description

Ho: OR=1

Ha: not equal to 1

Usage

RelativeRisk.Equality(alpha, beta, or, k, pt, pc)

Arguments

alpha	significance level
beta	power = 1-beta
or	or=pt(1-pc)/pc(1-pt)
k	k=nT/nC
pt	the probability of observing an outcome of interest for a patient treatment by a test treatment
pc	the probability of observing an outcome of interest for a patient treatment by a control
