Dear ElMaestro,

❝ I am not a SAS user but have noted that with SAS/Proc Power you can calculate sample size expressed as number of comparisons (or comparison pairs) for a given level of power while taking correlation into consideration. This seems relevant since in a 222BE-study the data are generally positively correlated within subject.

Could you please elaborate? I haven't yet discovered such things in Proc Power.

❝ I wonder what the equations then look like? Tried to look at the online manuals etc, but clearly the power to know is sending on frequencies at which I can't receive. ...

Me too .
