Covariance matrix functions of isotropic vector random fields
(Taylor & Francis Group, 20140515)An isotropic scalar or vector random field is a secondorder random field in (d > 2), whose covariance function or direct/cross covariance functions are isotropic. While isotropic scalar random fields have been well developed ... 
Hyperbolic vector random fields with hyperbolic direct and cross covariance functions
(Taylor & Francis, 20120626)This article introduces the hyperbolic vector random field whose finitedimensional distributions are the generalized hyperbolic one, which is formulated as a scale mixture of Gaussian random fields and is thus an elliptically ... 
Student's t vector random fields with powerlaw and loglaw decaying direct and cross covariances.
(Taylor & Francis, Inc, 20130101)This article deals with the Student's t vector random field, which is formulated as a scale mixture of Gaussian vector random fields, and whose finitedimensional distributions decay in powerlaw and have heavy tails. There ...
