Max-stable processes and stationary systems of Lévy particles

open access: yesStochastic Processes and Their Applications, 2015
We study stationary max-stable processes $\{η(t)\colon t\in\mathbb R\}$ admitting a representation of the form $η(t)=\max_{i\in\mathbb N}(U_i+ Y_i(t))$, where $\sum_{i=1}^{\infty} δ_{U_i}$ is a Poisson point process on $\mathbb R$ with intensity ${\rm e}^{-u} {\rm d} u$, and $Y_1,Y_2,\ldots$ are i.i.d.\ copies of a process $\{Y(t)\colon t\in\mathbb R\}$

Spectral representations of sum- and max-stable processes [PDF]

open access: yesExtremes, 2009
Spectral representations of symmetric \(\alpha\)-stable (S\(\alpha\)S) and max-stable stochastic processes are considered. An association between a max-stable and the corresponding S\(\alpha\)S process is established in terms of spectral measures of their finite-dimensional distributions.

Max-stable processes

2020
The first class of regularly varying time series we will investigate is the class of max-stable processes. These processes can be viewed as ideal models of heavy tailed time series.

Crossings of max-stable processes

Journal of Applied Probability, 1994
The expected number of upcrossings for a max-stable process is computed and compared with known results for stable processes. Asymptotically the formulas are of the same order.

Tukey max-stable processes for spatial extremes

Spatial Statistics, 2016
Abstract We propose a new type of max-stable process that we call the Tukey max-stable process for spatial extremes. It brings additional flexibility to modeling dependence structures among spatial extremes. The statistical properties of the Tukey max-stable process are demonstrated theoretically and numerically.

Regional Modelling of Extreme Storms Via Max-Stable Processes

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1993
SUMMARY Asymptotic models for extremes of random processes often form the basis for estimating the extremal behaviour of environmental phenomena. Most such phenomena have a spatial dimension, and the aim of this paper is to develop a procedure for modelling in continuous space the spatial dependence within extreme events.
