Non-stationary Spatio-Temporal Modeling Using the Stochastic Advection-Diffusion Equation
Martin Outzen Berild, Geir-Arne Fuglstad
We construct flexible spatio-temporal models through stochastic partial differential equations (SPDEs) where both diffusion and advection can be spatially varying. Computations are…
Spatially Varying Anisotropy for Gaussian Random Fields in Three-Dimensional Space
Martin Outzen Berild, Geir-Arne Fuglstad
Isotropic covariance structures can be unreasonable for phenomena in three-dimensional spaces such as the ocean. In the ocean, the variability of the response may vary with depth,…
Importance Sampling with the Integrated Nested Laplace Approximation
Martin Outzen Berild, Sara Martino, Virgilio Gómez-Rubio +1
The Integrated Nested Laplace Approximation (INLA) is a deterministic approach to Bayesian inference on latent Gaussian models (LGMs) and focuses on fast and accurate approximation…
