Hi All,

Below is the power reported for the assumed parameters with different software.

» From the research 2x2x2 (34 - balanced) for power estimation the following results are taken: β=0.20, α=0.05, CV = 0.32, PE = 0.92
» FARTSSIE17: 55%
» R: 55%
» WinNonLin: Power_80_20: 89%

Can you pls guide for FARTSSIE and R which method for power estimation is being used.

Currently i am cross verifying power value with the published paper of the potvin for two stage. They had calculated power with modification of Hauschke et al. For example if i take N=12, CV=40% and ratio 95% power by method C is reported to be 0.7505. For the same parameters power by FARTSSIE is -24.19%.
