Dear Detlew,

» 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.

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.

On two occasions I have been asked,—“Pray, Mr. Babbage,
if you put into the machine wrong figures,…
will the right answers come out?”

I am not able rightly to apprehend the kind of confusion of ideas
that could provoke such a question.    Charles Babbage
