Credit scoring refers to the collection of quantitative techniques used to assess the risk of lending to consumers, and it stands as one of the most successful applications of statistical and operations research modeling in modern finance. At its core, the objective is to assign a probability of default to a loan applicant. As Thomas explains, this probability is not arbitrary; it depends on a relatively large number of variables that determine an individual's ability to repay debt.

Credit Scoring and Its Applications is widely regarded as a essential text for professionals and academics in the banking, finance, and risk management sectors. Written by Lyn C. Thomas, a leading authority in mathematical finance, the book bridges the gap between the theoretical mathematical models used to predict default and the practical realities of running a lending business. It provides a rigorous yet accessible framework for understanding how lenders decide who gets credit, how much they get, and at what price.
At its simplest, a credit score is a statistical number that represents the likelihood a borrower will fail to repay a debt as agreed. L.C. Thomas emphasizes that a score is never a judgment of character but a probabilistic forecast based on historical data.
