Introduction to Extreme Value Theory: Applications to Risk Analysis and Management

One of the main issues in the statistical literature of extremes concerns the tail index estimation, which governs the probability of extreme occurrences. This estimation relies heavily on the determination of a threshold above which a Generalized Pareto Distribution GPD can be fitted. We introduce here a new and practically relevant method belonging to this second class. It is a self-calibrating method for modeling heavy tailed data, which we developed with N.

Debbabi and M. Effectiveness of the method is addressed on simulated data, followed by applications in neuro-science and finance. Results are compared with those obtained by more standard EVT approaches. Then we turn to the notion of dependence and the various ways to measure it, in particular in the tails. Through examples, we show that dependence is also a crucial topic in risk analysis and management.

Underestimating the dependence among extreme risks can lead to serious consequences, as for instance those we experienced during the last financial crisis. We introduce the notion of copula, which splits the dependence structure from the marginal distribution, and show how to use it in practice.

Taking into account the dependence between random variables risks allows us to extend univariate EVT to multivariate EVT.

We only give the first steps of the latter, to motivate the reader to follow or to participate in the increasing research development on this topic. Unable to display preview. Download preview PDF.

Introduction to Extreme Value Theory: Applications to Risk Analysis and Management

He was head of the Department of Mathematics and Statistics from His research expertise is in extreme value theory, methods and its applications. His research is driven by new problems arising from applications such as oceanography, hydrology, climatology, reliability, economics, reinsurance, finance, medicine and sport. He is mainly interested in teaching at the more mathematical end of probability and statistics. He has particular interest in teaching at the interface between probability models and statistical inference and engagement with applications. He is line manager of the CDT administrative and support staff and course director and tutor. Read More.

From the beginning, the aim of the Journal is to foster academic research by publishing original research articles that meet the highest analytical standards, and provide new insights that contribute and spread the business management knowledge. ERMBE is an international peer-reviewed open access journal. The articles published are related with any specialities in the fields of the Business Economics accounting, business management, finance, human resource management, marketing, operations management, organization theory, strategic management, etc. The target audience is constituted by academics and researchers belonging to any university and by professionals and executives from the business world. The last global financial crisis — has highlighted the weaknesses of value at risk VaR as a measure of market risk, as this metric by itself does not take liquidity risk into account. To address this problem, the academic literature has proposed incorporating liquidity risk into estimations of market risk by adding the VaR of the spread to the risk price.


Extreme Value Modeling and Risk Analysis: Methods and Applications presents a broad overview of statistical modeling of extreme events.

Box , Boulder, CO , U. Concurrently high values of the maximum potential wind speed of updrafts W max and 0—6 km wind shear Shear have been found to represent conducive environments for severe weather, which subsequently provides a way to study severe weather in future climates. The approach is based on the Heffernan and Tawn conditional extreme value model.

Сьюзан прошла мимо него с поразившим его выражением человека, потрясенного предательством. Коммандер не сказал ни слова и, медленно наклонившись, поднял пейджер. Новых сообщений не. Сьюзан прочитала их. Стратмор в отчаянии нажал на кнопку просмотра.

А что, подумала Сьюзан, если броситься мимо него и побежать к двери. Но осуществить это намерение ей не пришлось. Внезапно кто-то начал колотить кулаком по стеклянной стене. Оба они - Хейл и Сьюзан - даже подпрыгнули от неожиданности. Это был Чатрукьян.
