Dear Helmut,

Thank you very much for the clarification. One more last question...

» » » Honestly, I have no clue how to modify the models given in the progesterone-guidance.
»
» Specifically the scaling-part…
» For the ABE part (if swR <0.294) like the FDA’s Model II:
  • fixed:
    » Group, Sequence, Treatment, Period (nested within Group), Group-by-Sequence Interaction
    »
  • random:
    » Subject (nested within Group × Sequence)


But as per Progesterone Guidance, Treatment as random term in Average BE.

Please see model SAS code from guidance.

MODEL LAUCT = SEQ PER TRT/ DDFM=SATTERTH;
RANDOM TRT/TYPE=FA0(2) SUB=SUBJ G;


As per your version, Subject (nested within Group × Sequence) is the random term.

Now am Confused:ponder:,Which is the correct one?

Best Regards,
GM

The rise of biometry in this 20th century,
like that of geometry in the 3rd century before Christ,
seems to mark out one of the great ages or critical periods
in the advance of the human understanding.    R.A. Fisher
