Is it possible (or meaningful) to have a variable both as a nesting
variable AND a predictor in a three-level model?

I have a three-level model with 305 observations nested within
segments of the study (segment A and segment B), which are nested in
31 persons.  id is the person id.

So the form of the model is something like:
gllamm drivesf gender aldh2cent braccent, i(segment id) family(binom)
link(logit) eform

But can I also put segment as a variable in the model to see its
direct effect on the dependent variable, contrasting segment B against
segment A?

I want to put it both as a nesting variable AND a predictor in the
model.  Is that viable?
