Web1 dec. 2024 · We implemented the (AIC-based) constant weights combination rule, as well as the (deviance-based) probabilistic weights combination rule. At each draw t, the model-averaged prediction y ∼ t was set to y ̂ l t with probability λ l [t]. For the constant weights rule: λ l t = w l ∼, where the constant AIC-based weights were reported in Table 2. http://www.sthda.com/english/articles/38-regression-model-validation/158-regression-model-accuracy-metrics-r-square-aic-bic-cp-and-more/
