Appendix H. A summary of the model selection for the site-scale mortality analysis.
Comparison of
multiple regression
models for large scale instantaneous mortality rate based on monthly
surveys of
recruit and subadult density in 2004. Covariates
are settler density (D), predator abundance (P) and
habitat
rugosity (R). AIC difference (
) is the
difference between the AICc of model i and the lowest AICc observed. Akaike
weight (wi)
is calculated as the model likelihood, exp(-
/ 2), normalized by the sum of all model
likelihoods; values close to
1 indicate greater confidence in the selection of a model.
