Dear Helmut!

❝ ❝ PowerTOST V1.2-07 is on the way.

❝ THX!


You are welcome. But wait until it arrives really.

❝ ❝ First impression concerning TIE (n=24, nsims=1E6):

❝ ❝     CV   theta0      TIE

❝ ❝ 0.400  1.250000 0.137350


❝ Terrible! In their attempt to be more conservative they are shooting themselves in the foot. The same story over and over again. :no:


Exactly.

But the picture changes if they claim the same hokus pokus like "consumer risk model" and "implementation" as in the paper
Davit et al.
"Implementation of a Reference-Scaled Average Bioequivalence Approach for Highly Variable Generic Drug Products by the US Food and Drug Administration"
AAPS Journal, Vol. 14, No. 4, December 2012

p(BE) at the original EMA widened acceptance limits, again n=24, design="2x3x3" (partial replicate), nsims=1E6:
     CV   theta0    p(BE)
 0.2500 1.250000 0.050508
 0.2750 1.250000 0.050839
 0.3000 1.250000 0.053183
 0.3250 1.272300 0.039390
