S × F interaction [Design Issues]
❝ I don't understand the subject-by-formulation effect, …
❝ … can it only be studied in full replicated designs?
❝ If the subject-by-formulation effect is the change between test and reference difference means from one subject to another, in a 2x2 design it should be possible to study it. Right?
Adding S × F will not work. Didn’t try it yet. Either you get zero degrees of freedom in a fixed effects model or a mixed-effects model will collapse.
❝ And in that case it could also be measured in partial replicate. Right?
