Power using a confidence interval of previous 2x2 study
It calculates power for the bioequivalence test on ratio using a confidence interval of previous 2x2 study.
pow2x2ci(n1, n2, LL, UL, Alpha = 0.1)
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 |
It calculates power of sample size (n per group) with CV.
Returns power [0, 1)
