ABSTRACT We aim at analysing geostatistical and areal data observed over irregularly shaped spatial domains and having a distribution within the exponential family. We propose a generalized additive model that allows to account for spatially varying covariate information. The model is fitted by maximizing a penalized log-likelihood function, with a roughness penalty term that involves a differential quantity of the spatial field, computed over the domain of interest. Efficient estimation of the…

This work gives an overview of an innovative class of methods for the analysis of spatial and of functional data observed over complicated two‐dimensional domains. This class is based on regression
Generalized Spatially Varying Coefficient Models
Abstract In this article, we introduce a new class of nonparametric regression models, called generalized spatially varying coefficient models (GSVCMs), for data distributed over complex domains. For
Nonparametric density estimation over complicated domains
TLDR
The proposed nonparametric method efficiently deals with data scattered over regions having complicated shapes, featuring complex boundaries, sharp concavities or holes, and captures very well complicated signals having multiple modes with different directions and intensities of anisotropy.
A novel approach to the analysis of spatial and functional data over complex domains
TLDR
This work in particular focuses on data displaying complex spatial dependencies, where the complexity can for instance be due to the complex physics of the problem or the non-trivial conformation of the domain where the data are observed.
A phase-field model for liquid–gas mixtures: mathematical modelling and discontinuous Galerkin discretization
TLDR
A phase-field approach that might also provide a description of the expansion stage of a metal foam inside a hollow mold and an energy-based numerical scheme that preserves the mass conservation property and the energy dissipation law of the original system are proposed.

TLDR
It is shown that, using an approximate stochastic weak solution to (linear) stochastically partial differential equations, some Gaussian fields in the Matérn class can provide an explicit link, for any triangulation of , between GFs and GMRFs, formulated as a basis function representation.

Thin plate regression splines
TLDR
The production of low rank smoothers for d’≥ 1 dimensional data, which can be fitted by regression or penalized regression methods, are discussed, which allow the use of approximate thin plate spline models with large data sets, and provide a sensible way of modelling interaction terms in generalized additive models.
