The credibility approach to experience rating

Summary Chapter 1 presents the problem of experience rating and the objective of credibility theory. In Chapter 2 the so-called “limited fluctuation credibility theory” is presented briefly. The far more important and developed “greatest accuracy credibility theory” is introduced in Chapter 3. The discussion in Chapters 1–3 is carried through with a minimum of mathematics, the aim being to explain the basic ideas and techniques. A fuller account of the greatest accuracy theory is given in Chapter 4. The division of the matter into paragraphs reflects the distinction between what can be called the classical or empirical Bayes point of view and the (purely) Bayesian point of view. In Chapter 5 are mentioned some selected problems related to practical applications of the theory.
