Table 3.

Nine a priori candidate models for male (a) and female (b) owl monkeys ranked by their corrected Akaike Information Criteria (AICc) values. Models that fell below a delta AICc of 10, and thus did not meet our a priori criteria for further consideration, are shaded in grey.

K = number of estimated parameters in the model

AICc = corrected Akaike Information Criteria for the model

Delta AICc = Difference between the model and the “best model” (model with lowest AICc) in the candidate set

Log-Likelihood = the relative likelihood of the model

Cum. Weight = the cumulative Akaike weights of model (when sorted from lowest to highest AICc)
