bi2aeq1 {EQUIVNONINF}R Documentation

Power of the exact Fisher type test for equivalence

Description

The function computes exact values of the power of the randomized UMPU test for equivalence in the strict (i.e. two-sided) sense of two binomial distributions and the conservative nonrandomized version of that test. It is assumed that the samples being available from both distributions are independent.

Usage

bi2aeq1(m,n,rho1,rho2,alpha,p1,p2)

Arguments

m

size of Sample 1

n

size of Sample 2

rho1

lower limit of the hypothetical equivalence range for the odds ratio

rho2

upper limit of the hypothetical equivalence range for the odds ratio

alpha

p1

true success rate in Population 1

p2

true success rate in Population 2

Value

m

size of Sample 1

n

size of Sample 2

rho1

lower limit of the hypothetical equivalence range for the odds ratio

rho2

upper limit of the hypothetical equivalence range for the odds ratio

alpha

significance level

p1

true success rate in Population 1

p2

true success rate in Population 2

POWNR

Power of the nonrandomized version of the test

POW
