Document Details : Title: Multivariate Counting Processes Subtitle: Copulas and Beyond Author(s): BÄUERLE, N. , GRÜBEL, R. Journal: ASTIN Bulletin Volume: 35 Issue: 2 Date: November 2005 Pages: 379-408 DOI: 10.2143/AST.35.2.2003459 Abstract : Multivariate stochastic processes with Poisson marginals are of interest in insurance and finance; they can be used to model the joint behaviour of several claim arrival processes, for example. We discuss various methods for the construction of such models, with particular emphasis on the use of copulas. An important class of multivariate counting processes with Poisson marginals arises if the events of a background Poisson process with constant intensity are moved forward in time by a random amount and possibly deleted; here we think of the events of the background process as triggering later claims in different categories.We discuss structural aspects of these models,their dependence properties together with stochastic order aspects, and also some related computational issues. Various actuarial applications are indicated. |
