Hi ElMaestro,

» I could be wrong but...

We all may be but…

» PASS may be assuming this is a case of two sample t-test-like-scenario,…

It does (according to the manual and given in the output).

» … where it does not take into consideration that the actual model causes additional reduction of df's.

Yep, that’s the point! It gives me an answer to a question I did not ask (a model nobody uses for ages). Since I played around with the trial version, I can now say that it is a black 📦.
At least for the replicate designs the carryover model is hardcoded, not specified in the manual, and there is no way to change that.
I just sent an email to NCSS’ support asking for a clarification.

» You may be able to approximately reproduce PASS' result if you can override the df's in PowerTOST.


» I would still anyday say PowerTOST is more right than PASS, of course.


I like this one:
Of course, PASS passes IQ and OQ. Remember what you once wrote?

deliberate, contrived and dishonest—but the myth—
