Dear all,

I have a question that is probably specific to meta regression analyses.

I refer to Feld & Heckemeyer (2011) who are presenting in Figure 2 two models as follows:

(1) Array


(2) Array



(1) is here the fixed effects model and (2) the mixed or random effects model.

My question here is probably simple for most of you: When I chose my moderators, is it correct to regress (1) with -areg- and (2) with -reg-? If not, would you have any suggestion for a better approach?

Thanks in advance and best regards
