Multilevel approximation of Gaussian random fields: Covariance compression, estimation and spatial prediction

Helmut Harbrecht, Lukas Herrmann, Kristin Kirchner +1

Centered Gaussian random fields (GRFs) indexed by compacta such as smooth, bounded Euclidean domains or smooth, compact and orientable manifolds are determined by their covariance…

Equivalence of measures and asymptotically optimal linear prediction for Gaussian random fields with fractional-order covariance operators

David Bolin, Kristin Kirchner

We consider Gaussian measures $μ, μ ~$ on a separable Hilbert space, with fractional-order covariance operators $A^{- 2 β}$ resp. $A ~^{- 2 β ~}$ , and derive necessary an…
