Causal inference with spatio‐temporal data: Estimating the effects of airstrikes on insurgent violence in Iraq [PDF]

open access: yesJournal of the Royal Statistical Society: Series B (Statistical Methodology), 2020
Many causal processes have spatial and temporal dimensions. Yet the classic causal inference framework is not directly applicable when the treatment and outcome variables are generated by spatio‐temporal point processes.

Scalable Bayesian Transport Maps for High-Dimensional Non-Gaussian Spatial Fields [PDF]

open access: yesJournal of the American Statistical Association, 2021
A multivariate distribution can be described by a triangular transport map from the target distribution to a simple reference distribution. We propose Bayesian nonparametric inference on the transport map by modeling its components using Gaussian ...

Inferring Processes from Spatial Patterns: The Role of Directional and Non–Directional Forces in Shaping Fish Larvae Distribution in a Freshwater Lake System

open access: yesPLoS ONE, 2012
Larval dispersal is a crucial factor for fish recruitment. For fishes with relatively small-bodied larvae, drift has the potential to play a more important role than active habitat selection in determining larval dispersal; therefore, we expect small-bodied fish larvae to be poorly associated with habitat characteristics.

REHEATFUNQ (REgional HEAT-Flow Uncertainty and aNomaly Quantification) 2.0.1: a model for regional aggregate heat flow distributions and anomaly quantification [PDF]

open access: yesGeoscientific Model Development
Surface heat flow is a geophysical variable that is affected by a complex combination of various heat generation and transport processes. The processes act on different lengths scales, from tens of meters to hundreds of kilometers.

MADNet 2.0: Pixel-Scale Topography Retrieval from Single-View Orbital Imagery of Mars Using Deep Learning

open access: yesRemote Sensing, 2021
The High-Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter provides remotely sensed imagery at the highest spatial resolution at 25–50 cm/pixel of the surface of Mars.

Modeling spatial tail dependence with Cauchy convolution processes

open access: yes, 2022
We study the class of dependence models for spatial data obtained from Cauchy convolution processes based on different types of kernel functions. We show that the resulting spatial processes have appealing tail dependence properties, such as tail ...

The impact of experimental design choices on parameter inference for models of growing cell colonies [PDF]

open access: yesRoyal Society Open Science, 2018
To better understand development, repair and disease progression, it is useful to quantify the behaviour of proliferative and motile cell populations as they grow and expand to fill their local environment.

Bayesian Inference and Model Assessment for Spatial Point Patterns Using Posterior Predictive Samples

open access: yes, 2017
. Spatial point pattern data describes locations of events observed over a given domain, with the number of and locations of these events being random.

Bayesian inference for high-dimensional nonstationary Gaussian processes

open access: yesJournal of Statistical Computation and Simulation, 2019
In spite of the diverse literature on nonstationary spatial modelling and approximate Gaussian process (GP) methods, there are no general approaches for conducting fully Bayesian inference for moderately sized nonstationary spatial data sets on a ...

Inferring spatial causations from spatial associations considering spatial lags: a case study of geohazards in Yunnan, China

open access: yesAnnals of GIS
The inference of causation is essential for interpretable scientific research and evidence-based policymaking. Existing causal methods – including those based on intervention, forecasting, and graph models – have achieved considerable success in non ...
