Table C2.

Kitten survival models to examine the effects of age (3-month time step). For each model, we present the number of parameters (K), the difference from the top model in second-order Quasi-Akaike’s Information Criterion (ΔQAIC_c), the model QAIC_c weight, and the estimate of annual kitten survival with standard error. See Table C1 for descriptions of models. The base models selected are in bold.
