Doubly Stochastic Compound Poisson Processes in Extreme Value TheoryHelena FerreiraUniversidade da Beira Interior,R. Marquês d'Ávila e Bolama, 6200 Covilh\ a - PORTUGAL Abstract: For some linear models, chain-dependent sequences and doubly stochastic max-autoregressive processes, which do not satisfy the long range dependence condition $\Delta(u_{n})$ from Hsing {\sl et al.} ([7]), the sequence $\{S_{n}\}_{n\ge1}$, of point processes of exceedances of a real level $u_{n}$ by $X_{1},...,X_{n}$, $n\ge1$, converges in distribution to a compound Poisson process with stochastic intensity. Keywords: Extreme value theory; point processes; mixtures of distributions. Classification (MSC2000): 60F05, 60G55 Full text of the article:
