On Bayesian Mixture Credibility
We introduce a class of Bayesian infinite mixture models first introduced by Lo (1984) to determine the credibility premium for a non-homogeneous insurance portfolio. The Bayesian infinite mixture models provide us with much flexibility in the specification of the claim distribution. We employ the sampling scheme based on a weighted Chinese restaurant process introduced in Lo et al. (1996) to e...
متن کاملEvidence and Credibility: Full Bayesian Significance Test for Precise Hypotheses
A Bayesian measure of evidence for precise hypotheses is presented. The intention is to give a Bayesian alternative to significance tests or, equivalently, to p-values. In fact, a set is defined in the parameter space and the posterior probability, its credibility, is evaluated. This set is the “Highest Posterior Density Region” that is “tangent” to the set that defines the null hypothesis. Our...
متن کاملBayesian Credibility Modeling for Personalized Recommendation in Participatory Media
In this paper, we focus on the challenge that users face in processing messages on the web posted in participatory media settings, such as blogs. It is desirable to recommend to users a restricted set of messages that may be most valuable to them. Credibility of a message is an important criteria to judge its value. In our approach, theories developed in sociology, political science and informa...
متن کاملEmpirical Bayesian Credibility for Workers’ Compensation Classification Ratemaking
This paper demonstrates how a company can derive accurate classification relativities. The method uses an empirical Bay&an credibility formula as taken from the paper " Credibility for Loss Ratios " by Buhl-mann and St*,tub and modified by the IS0 Credibility Subcommittee. The data rc Ittired for this method can be purchased from the National Council. A classification review is performed on thr...
متن کاملA Bayesian Technique for Estimating the Credibility of question Answerers
We address the problem of ranking question answerers according to their credibility, characterized here by the probability that a given question answerer (user) will be awarded a best answer on a question given the answerer’s question-answering history. This probability (represented by θ ) is considered to be a hidden variable that can only be estimated statistically from specific observations ...
