complete or not [Study Assessment]
Dear Detlew,
I stand corrected.
Yep. In dose proportionality quite often (much) more levels than in BE come into play. The highest I have seen so far were five. Unbalanced & incomplete data are more the rule than an exception. That’s why I would prefer REML.
❝ ❝ My preference is REML/Satterthwaite because one could reproduce results in three different software packages.
❝ Emphasis by me.
❝
❝ That's not really a reason.
I stand corrected.

❝ The first sentences seem to point to an advantage of REML over ML estimation, left the question of the ddfm aside.
