Table 2.
(a) Summary of the model selection statistics for models predicting lifespan in males. The best five models are reported. Models are ranked by increasing order of their AICc values, which is the bias-corrected modified Akaike information criterion. Wi is the Akaike weight of the i model. (b) The estimates and relative importance of the various predictors across all models in the candidate set.
