Dear Helmut,

since you are very quick with answers even Saturday night, I'm not editing my previous post but commenting it here :-D

❝ Extracting the required stuff is beyond me. We had many discussions already in the forum and the verdict was “mixed effects models for BE are not possible in R”.

Hmmm...
If I remember correctly we were struggling with FDA model where sophisticated 'repeated' statement exists.
We successfully crosschecked EMA method B (simple mixed effects model with a Subject as random effect). So linear mixed effects models are possible until FDA-style is required :cool:

Kind regards,
Mittyri
