Abstract: | In this article, we propose a spatial model for analyzing extreme rainfall values over the Triveneto region (Italy). We assess
the existence of a long-term trend in the extremes. To integrate data coming from the different stations, we propose a hierarchical
model. At the first level, for each monitoring station we model data by making use of a generalized extreme value distribution;
at the second level, we combine results from the first stage by exploiting recent advances in modeling nonstationary spatial
random fields. |
