A Poisson cokriging method for bivariate count data
Elsevier (2023)Bivariate spatially correlated count data appear naturally in several domains such as ecology, economy and epidemiology. Current methods for analysing such data lack simplicity, interpretability and computational awareness. ... -
On potentially negative space time covariances obtained as sum of products of marginal ones
Springer Verlag (2008)Most of the literature on spatio-temporal covariance models proposes structures that are positive in the whole domain. However, problems of physical, biological or medical nature need covariance models allowing for ... -
Optimal dynamic spatial sampling
John Wiley & Sons Ltd (2016)This paper provides new tools for dynamic spatial sampling designs to find the optimal spatial mean estimation and the optimal spatial prediction, based on the temporal variation of the spatial dependence structure. We ... -
Recent advances to model anisotropic space–time data
Springer-Verlag (2008-05)Building new and flexible classes of nonseparable spatio-temporal covariances and variograms has resulted a key point of research in the last years. The goal of this paper is to present an up-to-date overview of recent ...
