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.
