Generalized linear models (GLMs) predicting the probability of a male (a) or a female (b) elk being shot during the hunting season. The top-ranked model (in bold) selected for each sex using Akaike information criterion (AIC) was used to estimate parameters (reported below each panel). W_i are Akaike weights.
