Modelo Gumbel multivariado com efeitos aleatórios espacialmente compartilhados

Abstract

In this work were proposed a multivariate model for predition of spatially dependents extreme values. The model was constructed by conditioning a Gumbel distribution with respect to spatially shared random effect following an alpha-stable distribution. Some properties of this new model are presented and a MCEM algorithm was developed for the estimation of the parameters. The model was illustrated by the spatio-temporal prediction of maximum temperature in the Amazonas state, Brazil
