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 s_wR <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,Which is the correct one?
