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 …

Webcredibility theory in a multivariate context The calculation of the conditional MSEP for the predictor of the ultimate claim for a whole portfolio of several correlated run-off portfolios is more sophis-ticated than for only one run-off portfolio.

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. Webcredibility weighted rate change indications were calculated: Credibility weighted rate change = Zi x Ri + (1 − Zi) x (+2.0 %) . indication for territory i The credibility weights Zi were calculated from the formula Zi = ni / (ni + K ) where ni was the number of insured vehicles in the territory during the three-year data collection period.
