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.


Maybe.

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


:cool:

I like this one:

Of course, PASS passes IQ and OQ. Remember what you once wrote?
