Abstract

We propose a new fitting method to estimate the set of second-order parameters for the class of homogeneous spatiotemporallog-Gaussian Cox point processes. With simulations, we show that the proposed minimum contrast procedure,based on the spatio-temporal pair correlation function, provides reliable estimates and we compare the results with thecurrent available methods. Moreover, the proposed method can be used in the case of both separable and non-separableparametric specifications of the correlation function of the underlying Gaussian Random Field. We describe earthquakesequences comparing several Cox model specifications.
