WebD x y has simple relationship with the c-index: D x y = 2 ( c − 0.5). A D x y of 0 occurs when the model's predictions are random and when D x y = 1, the model is perfectly discriminating. In this case, the c-index is 0.693 which is slightly better than chance but a c-index of > 0.8 is good enough for predicting the outcomes of individuals. Webin the context of an individual defaulting on their credit is the odds of the credit defaulting. The logistic regression prediction model is ln (odds) =− 8.8488 + 34.3869 x 1 − 1.4975 x 2 − 4.2540 x 2.The coefficient for credit utilization is 34.3869. This can be interpreted as the average change in log odds is 0.343869 for each percentage increase in credit utilization.
