Large Wave Direction Data Modeling Using Wrapped Spatial Gaussian Markov Random Fields
Arnab Hazra
Statistical modeling of dependent directional data remains relatively underexplored, particularly in high-dimensional spatial settings. Existing approaches for spatial angular data…

Latent Gaussian Models for High-Dimensional Spatial Extremes
Arnab Hazra, Raphaël Huser, Árni V. Jóhannesson
In this chapter, we show how to efficiently model high-dimensional extreme peaks-over-threshold events over space in complex non-stationary settings, using extended latent Gaussian…

A semiparametric spatiotemporal Bayesian model for the bulk and extremes of the Fosberg Fire Weather Index
Arnab Hazra, Brian J. Reich, Benjamin A. Shaby +1
Large wildfires pose a major environmental concern, and precise maps of fire risk can improve disaster relief planning. Fosberg Fire Weather Index (FFWI) is often used to measure w…
