We often only use estimates of fixed-effects to answer one or more research
questions in a meta-analysis.
But is it also possible to specify one or more random effects to actually
answer one or more research questions in a meta-analysis?
If yes, then, which of the following should be a *priority* when fitting a
(A) Specifying one or more random effects based on the research questions?
(B) Specifying one or more random effects based on the fit of the model to
By *priority*, I mean deciding what to do when there is a conflict between
the above choices (e.g., A is desired, but B gives the superior fit).
