Dear Eva,

F is the ratio of the mean square of your factor, divided by the mean square of what you consider as the error factor. SAS divided the MS of the sequence effect (0.6105) by the MS of the residual error (0.2481). WinNonlin divided the sequence MS by the MS of subject(sequence) (0.2623). This is what SAS does in the second step I mentioned previously.

Helmut, I will let you explain why subject(sequence) should be used as an error term

Regards
Ohlbe
