pow2x2mse

Power using mean squared error (MSE) of previous 2x2 study

It calculates power for the bioequivalence test on ratio using mean squared error (MSE of previous 2x2 study.

pow2x2mse(n1, n2, mse, True.R = 1, Alpha = 0.1, ThetaL = 0.8, ThetaU = 1.25)

`n1`	Subject count of group 1
`n2`	Subject count of group 2
`mse`	Mean squared error
`True.R`	True ratio of test/reference
`Alpha`	Alpha level. This means (1 - alpha/2)*100 % confidence interval is given
`ThetaL`	Lower limit of equivalence criteria
`ThetaU`	Upper limit of equivalence criteria

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

Returns power [0, 1)
