Dear Detlew & Yura

❝ And tell us which version of WinNonlin you used for your calculations.

❝ AFAIK Phoenix had corrected this nonsense power calculations later on.


The additional result Power_TOST was introduced in Phoenix WinNonlin v6.4 (2014). During development it was cross-validated against power.TOST(..., method="nct"). ;-)
Power_80_20 (for the FDA’s 80/20-rule) is still there for backwards compatibility. Don’t use it.
