Hello Helmut: Yes; I did see that Formulation not Treatment later after lunch, but it still did not work. Then following your direction about Group being a classification variable (and including subject in model) I did get it to work.

Dependent hyothesis     NumDF Denomin     Fstat       p value

Ln(AUC)   int               1   64    11226.673       0

Ln(AUC)   Group             1   64        0.006028186 0.93835554

Ln(AUC)   Sequence          1   64        3.4513852   0.067800018

Ln(AUC)   Group*Sequence    1   64        0.000321727 0.9857451

Ln(AUC)   Group*Period      2   64        0.064946799 0.937179

Ln(AUC)   Formulation       1   64        0.36503556  0.54785867


Ln(AUC)   Formulation*Group 1   64        0.002630007 0.95925927

The formulation by group interaction p value was 0.95 for this composed data set.

Many thanks and also your sample size program in R works well: I have almost zero experience in R, but the reference you provided was easy to follow.

Here is the setup I used in Phoenix: Subject has to be mapped to get it to work (see link below)
