Cover Story: The concordance probability, also called the C-index, is a popular measure to capture the discriminatory ability of a predictive model. We have adapted the definition of this measure to the specific needs of the frequency and severity model, typically used during the technical pricing of a non-life insurance product. For the frequency model, three new types of the concordance probability are defined, designed to deal with the concept of exposure, i.e., the duration of a policy or insurance contract. Frequency data typically have a large sample size, and therefore, we present two fast and accurate estimation procedures for big data. We also present the concordance probability adapted for severity models. View this paper
