I'm used to HLM 7 software and now I'd like to switch to Stata, for multilevel modelling (xtmixed).
To give an example imagine I have students(level1) nested within schools (level2). In HLM I can easily add a second level variable (for instance schools beauty) choosing the equation of a coefficient (or intercept) which is at level 2.
Imagine I want to include the effect of school beauty in B0 (intercept). How can I do that in Stata?
