Extreme Value Theory for Hurwitz Complex Continued Fractions [PDF]

open access: yesEntropy, 2021
The Hurwitz complex continued fraction is a generalization of the nearest integer continued fraction. In this paper, we prove various results concerning extremes of the modulus of Hurwitz complex continued fraction digits. This includes a Poisson law and

Extreme Value Theory in Application to Delivery Delays [PDF]

open access: yesEntropy, 2021
This paper uses the Extreme Value Theory (EVT) to model the rare events that appear as delivery delays in road transport. Transport delivery delays occur stochastically.

Portfolio Tail Risk: A Multivariate Extreme Value Theory Approach [PDF]

open access: yesEntropy, 2020
This paper develops a method for assessing portfolio tail risk based on extreme value theory. The technique applies separate estimations of univariate series and allows for closed-form expressions for Value at Risk and Expected Shortfall. Its forecasting

Extreme value theory in emerging markets [PDF]

open access: yesEkonomski Anali, 2010
This paper investigates the performance of extreme value theory (EVT) with the daily stock index returns of four different emerging markets. The research covers the sample representing the Serbian (BELEXline), Croatian (CROBEX), Slovenian (SBI20), and ...

Applications of Extreme Value Theory in Public Health. [PDF]

open access: yesPLoS ONE, 2016
ObjectivesWe present how Extreme Value Theory (EVT) can be used in public health to predict future extreme events.MethodsWe applied EVT to weekly rates of Pneumonia and Influenza (P&I) deaths over 1979-2011.

Modelling the species-area relationship using extreme value theory [PDF]

open access: yesNature Communications
The nested species-area relationship, obtained by counting species in increasingly larger areas in a nested fashion, exhibits robust and recurring qualitative and quantitative patterns.

Extreme value theory inspires explainable machine learning approach for seizure detection [PDF]

open access: yesScientific Reports, 2022
Epilepsy is one of the brightest manifestations of extreme behavior in living systems. Extreme epileptic events are seizures, that arise suddenly and unpredictably.

EXTREME VALUE THEORY WITH OPERATOR NORMING. [PDF]

open access: yesExtremes (Boston), 2013
A new approach to extreme value theory is presented for vector data with heavy tails. The tail index is allowed to vary with direction, where the directions are not necessarily along the coordinate axes. Basic asymptotic theory is developed, using operator regular variation and extremal integrals.

Distributions conditioned on extrapolated events via copula and extreme value theory [PDF]

open access: yesMethodsX
In an interaction between road users, the proximity and speed are two interdependent dimensions which can be captured by a type of multivariate distribution called Copula. Copula requires all marginal distribution functions to be known.
