Hi Dave,

❝ ❝ D. Labes:

❝ ❝ BTW: What is missing is explicit code for ABE evaluation for the partial replicate design ...

❝

❝ The explicit code for this is on the last page (page 9) of the progesterone guidance. It's just the unscaled approach. You can use that method for both 4-period and 3-period designs.

(underlined by me)

I do not believe that. We have experimented with the FDA code on partial replicate design here in the forum and got some strange results. See f.i. here and here.
IMHO this is due to the fact that the intra-subject variance for Test is not identifiable in this design.

BTW: Regarding the sample size question of my very dear friend KR have a look into this tread.
