A two-stage Bayesian modelling framework with applications in spatial epidemiology [PDF]

open access: yes
This thesis proposes a framework for doing two-stage modelling in spatial epidemiology, whose main goal is to understand the association between a covariate of interest, which is modelled in the first stage, and health outcomes, which is modelled in the ...

A Bayesian INLA-SPDE Approach to Spatio-Temporal Point-Grid Fusion with Change-of-Support and Misaligned Covariates

open access: yes
We propose a spatio-temporal data-fusion framework for point data and gridded data with variables observed on different spatial supports. A latent Gaussian field with a Matérn-SPDE prior provides a continuous space representation, while source-specific observation operators map observations to both point measurements and gridded averages, addressing ...

Improving Earthquake Disaster Models with Post-Event Data: Insights from the 2015 Gorkha, Nepal Earthquake [PDF]

open access: yes, 2019
Immense amounts of data are collected following earthquake disasters. Yet, it remains unclear how researchers’ might take full advantage of diverse post-disaster datasets. Using data from the 2015 Gorkha Nepal earthquake, this dissertation explores three

A comparison of extreme gradient and Gaussian process boosting for a spatial logistic regression on satellite data [PDF]

open access: yes
The paper compares two advanced boosting techniques, Extreme Gradient Boosting (XGBoost) and Gaussian Process Boosting (GPBoost), for spatial logistic regression models using satellite data.

Spatial data fusion adjusting for preferential sampling using INLA and SPDE

open access: yes
Spatially misaligned data can be fused by using a Bayesian melding model that assumes that underlying all observations there is a spatially continuous Gaussian random field process.
