ss2x2ci

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

sample size

Analyze bioequivalence study data with industrial strength. Sample size could be determined for various crossover designs, such as 2x2 design, 2x4 design, 4x4 design, Balaam design, Two-sequence dual design, and William design.
