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. WebMay 1, 2024 · Arguably almost all developments in modern credibility theory have been based on Bühlmann's fundamental Bayes approach to credibility. Despite its simple and widespread applicability, Bühlmann's approach leads to a linear Bayesian credibility estimator that is not robust and sensitive to heavy-tailed excess claims and may not … hutch anytime data packages
