1. Amazing, yes the "eval(metafor:::.MuMIn” did allow me to run your example and get model-averaged coefficient estimates! Wahoo!!

However, when I tried running a dredge on my own model, after 10+ hours it had still not finished running.

I’m wondering if this issue is because I am not model dredging, but using different model combinations by hand and trying to average those?
