Delta.AICc.Array |
Delta.AICc.Array is defined as the difference between the AICc value and the minimum AICc value among candidate models. |
For n models of interest, the Akaikei weight for the i th model is defined as w = exp(-0.5* Δ AICc_i)/ sum_i dAICc_i where Δ AICc_i is the difference of the AICc value between the the i th model and the best model. The weights can be used in model averaging in advanced.
