发帖数: 66 | 1 how to fit a mixed model with subject nested in treatment group, and time
points nested in visit? so, there are two treatment groups, subjects have 7
visits, each visit has 3 session (time points). Is there a way to specify
two nested effects? | x******6

Treatment group
subject
visit
session
if so, then I think you can do
repeated session / visit(subject) subject_ID(treatment_ID)

called HLM that handles 3-level models, but yours has 4 levels. I guess SAS
can handle this?
