Hi ElMaestro,

❝ But isn't all this due to SAS trying to create a within-s for A in the covariance matrix, which can't be optimized? It might very well be syntax-dependent, but I am not a SAS user so I do not know which syntax to apply to make SAS understand that only a within-s for B makes sense in V.

So the SAS code is deficient? FDA should point out the need for adjustment I think. Maybe I am too much of a novice in this aspect...

❝ Oh, and on a completely different note: Check AUC-extrapolations of subjs 67, 82.

Yeah I know, the PK data was pulled from the CRO so it was just a snapshot on my behalf for now. They just use WinNonlin to estimate t1/2 and roll out the results.

Oh I encountered another sneaky thing with a CRO, on the bioanalytical side. That's another story, maybe after Xmas I will bring it up...
