Operator-matched spatial regression
David Bolin
A standard spatial regression model , with covariates and a Gaussian random field with Matérn covariance, decouples covariate effects from spatial dependenc…
Gaussian Processes on Directed Metric Graphs
David Bolin, Alexandre de Bustamante Simas, Erik Karlsson Strandh +1
We introduce a statistical framework for Gaussian fields indexed at arbitrary edge locations on general compact directed metric graphs. The construction is based on a stochastic di…
Incorporating Correlated Nugget Effects in Multivariate Spatial Models: An Application to Argo Ocean Data
Damilya Saduakhas, David Bolin, Xiaotian Jin +2
Accurate analysis of global oceanographic data, such as temperature and salinity profiles from the Argo program, requires geostatistical models capable of capturing complex spatial…
Statistical inference for Gaussian Whittle-Matérn fields on metric graphs
David Bolin, Alexandre Simas, Jonas Wallin
Whittle-Matérn fields are a recently introduced class of Gaussian processes on metric graphs, which are specified as solutions to a fractional-order stochastic differential equatio…
