Document Details : Title: On the Use of Conditional Specification Models in Claim Count Distributions: an Application to Bonus-Malus Systems Author(s): SARABIA, J.M. , GOMEZ-DENIZ, E. , VAZQUEZ-POLO, F.J. Journal: ASTIN Bulletin Volume: 34 Issue: 1 Date: May 2004 Pages: 85-98 DOI: 10.2143/AST.34.1.504956 Abstract : In this paper a new methodology using the conditional specification technique introduced by Arnold et al. (1999) is used to obtain bonus-malus premiums. A Poisson distribution for which the parameter is a function of the classical structure parameter is used and a new class of prior distribution arises in a natural way. This model contains, as a particular case, the classical compound Poisson model and is found to be much more robust than earlier ones. An example is given to illustrate our ideas. |
