Equivalence and orthogonality of Gaussian measures on spheres
Elsevier (2018-09)The equivalence of Gaussian measures is a fundamental tool to establish the asymptotic properties of both prediction and estimation of Gaussian fields under fixed domain asymptotics. The paper solves Problem 18 in the list ... -
Schoenberg coefficients and curvature at the origin of continuous isotropic positive definite kernels on spheres
Elsevier (2020)We consider the class Ψd of continuous functions that define isotropic covariance functions in the d-dimensional sphere Sd. We provide a new recurrence formula for the solution of Problem 1 in Gneiting (2013b), solved ...
