Isotropy, symmetry, separability and strict positive definiteness for covariance functions: a critical review

S De Iaco, D Posa, C Cappello, S Maggio - Spatial statistics, 2019 - Elsevier
Although isotropy, symmetry and separability are commonly assumed for practical reasons,
anisotropic, asymmetric and non-separable covariance functions are often more realistic; in …

Geostatistical methods for disease mapping and visualisation using data from spatio‐temporally referenced prevalence surveys

E Giorgi, PJ Diggle, RW Snow… - International Statistical …, 2018 - Wiley Online Library
In this paper, we set out general principles and develop geostatistical methods for the
analysis of data from spatio‐temporally referenced prevalence surveys. Our objective is to …

Assessing the calibration of multivariate probabilistic forecasts

S Allen, J Ziegel, D Ginsbourger - Quarterly Journal of the …, 2024 - Wiley Online Library
Rank and probability integral transform histograms are established tools to assess the
calibration of probabilistic forecasts. They not only check whether a forecast is calibrated, but …

Evaluation of ride-sourcing search frictions and driver productivity: A spatial denoising approach

N Zuniga-Garcia, M Tec, JG Scott, N Ruiz-Juri… - … Research Part C …, 2020 - Elsevier
This paper considers the problem of measuring spatial and temporal variation in driver
productivity on ride-sourcing trips. This variation is especially important from a driver's …

Flexible spatial covariance functions

AM Schmidt, P Guttorp - Spatial Statistics, 2020 - Elsevier
We focus on the discussion of modeling processes that are observed at fixed locations of a
region (geostatistics). A standard approach is to assume that the process of interest follows a …

Estimation of local anisotropy based on level sets

C Berzin - Electronic Journal of Probability, 2021 - projecteuclid.org
Consider an affine field X: R 2→ R, that is a process equal in law to Z (A. t), where Z is
isotropic and A: R 2→ R 2 is a linear self-adjoint transformation. The field X and …

The potential of ICESat-2 to identify carbon-rich peatlands in Indonesia

A Berninger, F Siegert - Remote Sensing, 2020 - mdpi.com
Peatlands in Indonesia are one of the primary global storages for terrestrial organic carbon.
Poor land management, drainage, and recurrent fires lead to the release of huge amounts of …

On some characteristics of gaussian covariance functions

S De Iaco, D Posa, C Cappello… - International Statistical …, 2021 - Wiley Online Library
The concepts of isotropy/anisotropy and separability/non‐separability of a covariance
function are strictly related. If a covariance function is separable, it cannot be isotropic or …
