I’m looking to plot / predict from stacked or averaged models in brms. I’ve computed model weights and two models have approximately similar model weights. My understanding is that in this situation, I should stack these models to take into account the uncertainty about the “preferred” model. The problem I’m having is, how do I go from getting the model weights (e.g., m1 = .54, m2, .46) to plotting / prediction of the stacked model. Any help on this would be super helpful; I’m new to stacking / model averaging so apologies if my questions don’t quite make sense.
