Analysing Extreme Rainfall via a Geometric Framework
Ryan Campbell, Kristina Grolmusova, Lydia Kakampakou +1
Motivated by the EVA 2025 Data Challenge, we address the problem of predicting extreme rainfall in the eastern United States using data from a large ensemble of climate model runs.…
Piecewise-linear modeling of multivariate geometric extremes
Ryan Campbell, Jennifer Wadsworth
A recent development in extreme value modeling uses the geometry of the dataset to perform inference on the multivariate tail. A key quantity in this inference is the gauge functio…
Statistical inference for radial generalized Pareto distributions and return sets in geometric extremes
Ioannis Papastathopoulos, Lambert de Monte, Ryan Campbell +1
We use a functional analogue of the quantile function for probability measures on to characterize a novel limit Poisson point process for radially recentred and resc…
Extreme value methods for estimating rare events in Utopia
L. M. André, R. Campbell, E. D'Arcy +6
To capture the extremal behaviour of complex environmental phenomena in practice, flexi\-ble techniques for modelling tail behaviour are required. In this paper, we introduce a var…
