Estimating covariance functions of multivariate skew-Gaussian random fields on the sphere
Alfredo Alegría, Sandra Caro, Moreno Bevilacqua +2
This paper considers a multivariate spatial random field, with each component having univariate marginal distributions of the skew-Gaussian type. We assume that the field is define…
Estimation and Prediction using generalized Wendland Covariance Functions under fixed domain asymptotics
M. Bevilacqua, T. Faouzi, R. Furrer +1
We study estimation and prediction of Gaussian random fields with covariance models belonging to the generalized Wendland (GW) class, under fixed domain asymptotics. As the Matérn…
Buhmann covariance functions, their compact supports, and their smoothness
E. Porcu, P. Zastavyi, M. Bevilacqua
We consider the Buhmann class of compactly supported radial basis functions, whih includes a wealth of special cases that have been studied in both numerical analysis and spatial s…
Maximum likelihood estimation for a bivariate Gaussian process under fixed domain asymptotics
Daira Velandia, François Bachoc, Moreno Bevilacqua +2
We consider maximum likelihood estimation with data from a bivariate Gaussian process with a separable exponential covariance model under fixed domain asymptotic. We first characte…
