In this thesis, we introduce a methodology based on zero-inflated survival data for the purposes of dealing with propensity to default (credit risk) in bank loan portfolios. Our approach enables us to accommodate three different types of borrowers: (i) individual with event at the starting time, i.e., default on a loan at the beginning; (ii) non-susceptible for the event of default, or (iii) susceptible for the event. The information from borrowers in a given portfolio is exploited through the joint modeling of their survival time, with a multinomial logistic link for the three classes. An advantage of our approach is to accommodate zero-inflated times, which is not possible in the standard cure rate model introduced by Berkson & Ga...
