A Logistic Regression model was used for classifying common brushtail possums into their two regions. The outcome variable takes value 1 if the possum was from Victoria and 0 otherwise. We consider five predictors: sex_male (an indicator for a possum being male), head length, skull width, total length, and tail length. A summary table is provided below. Estimate Std.
