Prior to his research, the standard approach to modeling credit defaults was logistic regression, which estimates the probability of default over a fixed period, often 12 months. In a series of influential papers starting in 1999, Thomas proposed that a proportional hazards model could be just as effective. This method, borrowed from survival analysis in medical statistics, does not just predict if a default will happen, but when it will happen.
