Power using a confidence interval of previous 2x2 study

Description

It calculates power for the bioequivalence test on ratio using a confidence interval of previous 2x2 study.

Usage

pow2x2ci(n1, n2, LL, UL, Alpha = 0.1)

Arguments

n1	Subject count of group 1
n2	Subject count of group 2
LL	Lower limit of the confidence interval of geometric mean ratio (Test/Reference)
UL	Upper limit of the confidence interval of geometric mean ratio (Test/Reference)
Alpha	Alpha level. This means (1 - alpha/2)*100 % confidence interval is given

Details

It calculates power of sample size (n per group) with CV.

Value

Returns power [0, 1)
