Buhlmann credibility theory

WebFeb 2, 2010 · Introduction to Buhlmann credibility. In this post, we continue our discussion in credibility theory. Suppose that for a particular insured (either an individual entity or a group of insureds), we have observed data (the numbers of claims or loss amounts). We are interested in setting a rate to cover the claim experience from the next period. WebCredibility theory is widely used in insurance. It is included in the examination of the Society of Actuaries and in the construction and evaluation of actuarial models. In particular, the Buhlmann credibility model has played a fundamental role in both actuarial theory and practice. It provides a mathematical rigorous procedure for deciding how much …

WebBuhlmann-Straub credibility. This motivates at least the hope that a similar shrinkage might be expected from a GLMM, where the math is no longer tractable in closed form. Demonstrate the application of a GLMM to a case study in which the hoped-for shrinkage is indeed observed and does indeed approximate the form of Buhlmann-Straub credibility.

In credibility theory, a branch of study in actuarial science, the Bühlmann model is a random effects model (or "variance components model" or hierarchical linear model) used to determine the appropriate premium for a group of insurance contracts. The model is named after Hans Bühlmann who first … See more Consider i risks which generate random losses for which historical data of m recent claims are available (indexed by j).
