Bayesian Analysis of Extreme Values by Mixture Modeling

Extremes, 2003
It is supposed that the observed exceedances over some fixed threshold are generated by a Poisson process with intensity \[ \Lambda_y= ( 1+\xi(y-\mu)/ \psi)^{-1/\xi}, \] where \(\mu\) is the location, \(\psi\) is the scale and \(\xi\) is the shape parameter.

Regional Extreme Value Analysis

2021
This chapter focuses on the occurrence of extreme natural hazards in non-instrumented locations, whose neighborhood contains sites for which measured data are available. The spatial regionalization approach developed here, which is based on the detection of regions that are homogeneous in terms of risk, allows to propose a localized quantification of ...

Extreme value analysis in biometrics

Biometrical Journal, 2009
AbstractWe review some approaches of extreme value analysis in the context of biometrical applications. The classical extreme value analysis is based on iid random variables. Two different general methods are applied, which will be discussed together with biometrical examples.

Extreme Value Analysis

2000
The extreme (upper or lower) parts of a sample, such as flood discharges; high concentration of air pollutants; claim sizes over a higher priority in reinsurance business; larger losses on financial markets; have exhibited an increasing risk potential during the last decades.

Extreme Value Analysis for Financial Risk Management

Annual Review of Statistics and Its Application, 2021
This article reviews methods from extreme value analysis with applications to risk assessment in finance. It covers three main methodological paradigms: the classical framework for independent and identically distributed data with application to risk estimation for market and operational loss data, the multivariate framework for cross-sectional ...

Trend Analysis of Extreme Values

2011
In Dierckx and Teugels (Environmetrics 2:1–26) we concentrated on testing whether an instantaneous change occurs in the value of the extreme value index. This short article illustrates with an explicit example that in some cases the extreme value index seems to change gradually rather than instantaneously.

IT Design for Resiliency Using Extreme Value Analysis

2021
Safety-critical systems are designed to operate millions of hours without losing or harming life. Millions of hours enable events with small occurrence probability to materialise. Owing to this, rare events have to be factored when designing for millions of safe operating hours.
