Considerations for assessing model averaging of regression coefficients

Abstract: Model choice is usually an inevitable source of uncertainty in model-based statistical analyses. While the focus of model choice was traditionally on methods for choosing a single model, methods to formally account for multiple models within a single analysis are now accessible to many researchers. The specific technique of model averaging was developed to improve predictive ability by combining predictions from a set of models. However, it is now often used to average regression coefficients across multiple m… Show more

“…To account for model‐based uncertainty with our models of EMR active season survival, and given our primary goal of prediction, we model‐averaged parameter estimates of the top 95% confidence model set (i.e., cumulative AIC c weight of models ≤0.95) (Symonds & Moussalli, ). We projected active season survival rates based on model‐averaged parameter estimates annually through 2100 using the adjusted future annual time series based on climate anomalies (Banner & Higgs, ). Thus, survival rates varied over space and time and incorporated the simulated future climate projections associated with winter minimum temperature, summer cumulative precipitation, and SPEI on an annual time‐step.…”

“…As the cut‐off value of ΔAICc ≤ 2 might be considered stringent, we also report the averaged estimates for models within ΔAICc ≤ 7 (see Data , but cf . Banner & Higgs, on averaging regression estimates). For red deer, the parameter estimates did not change.…”
