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 ... 
Logistic vector random fields with logistic direct and cross covariances
(Elsevier B.V., 201506)The logistic vector random field is introduced in this paper as a scale mixture of Gaussian vector random fields, and is thus a particular elliptically contoured (spherically invariant) vector random field. Such a logistic ... 
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 ...
