Credibility theory is a branch of actuarial mathematics concerned with determining risk premiums. [1] To achieve this, it uses mathematical models in an effort to forecast the number of insurance claims based on past observations.

1. Credibility Models This study note supplements the “Credibility” chapter of Foundations of Casualty Actuarial Science as a reading for the fourth CAS/SOA examination. Several important topics not covered in the Foundations text are presented here, including the Bühlmann-Straub credibility model and estimation of credibility formula ...

Develop an analytical framework to provide practitioners with an extensive actuarial analysis of applied credibility theory from the standpoint of example using intercompany lapse and mortality. Administer a survey to gauge the application of credibility theory in various actuarial tasks associated with managing life and annuity risks.

Credibility theory provides a convenient framework for combining the experience for an individual risk or class with other data to produce more stable and accurate estimates.

Credibility theory provides important tools to help the actuary deal with the randomness inherent in the data that he or she analyzes. Actuaries use past data to predict what

Recent U.S. Treasury regulations have detailed a credibility method to be applied to pension plan mortality assumptions, raising the importance of credibility for pension actuaries. This paper provides an overview of the most common credibility methods and a …

In this paper, we review the two most commonly used credibility methods: Limited Fluc- tuation and Greatest Accuracy (Buhlmann) credibility. Following the approach of Klugman et al. (2009), eral, qualitative observations. In addition, we use simulation to generate a universe of data and compute. following the approach of Klugman et al. (2009).

Abstract: This survey of actuarial credibility theory traces its origins, describes its evolutionary history, gives an account of its main issues and re-sults, and assesses its merits with a view to related work in statistical science. Key-words: Experience rating, limited fluctuation theory, greatest accuracy
