Abstract:
For the solution Y of a multivariate random recurrence model Yn = AnYn−1n in Rq we investigate the extremal behaviour of the process yn=z′*Yn, nε N, for z*ε Rq with |z| = 1. This extends results for positive matrices An. Moreover, we obtain explicit representations of the compound Poisson limit of point processes of exceedances over high thresholds in terms of its Poisson intensity and its jump distribution, which represents the cluster behaviour of such models on high levels. As a principal...     »
