EVA 2023 has been organised by Bocconi University. 

The conference brings together researchers in Extreme Value Theory, Methods and its Applications.

Its inception took place almost 40 years ago in Vimeiro, Portugal (1983). The photo below has been taken from the previous EVA conference edition:

Handling asymptotic theories in extremes: (multivariate) tail empirical and tail quantile processes

________________________________________________________________________________________

Instructor: Chen Zhou (Erasmus University Rotterdam)



Description: Extreme value statistics often rely on selected observations in the tail of a (multivariate) distribution. Observations are selected by using either the Peaks-over-threshold (POT) or the block maxima (BM) approaches. Statistical estimators are regarded as functional transformation of empirical or quantile processes formed based on such tail observations, the tail empirical and tail quantile processes. To establish asymptotic theories for most estimators, the fundamental tool is their asymptotic behavior.

In this tutorial, we start from asymptotic behavior of the weighted tail empirical and tail quantile processes based on independent and identically distributed observations. Then we discuss how to use them in proving asymptotic theories of typical extreme value estimators. The tutorial will also cover advanced tools such as multivariate tail empirical process and tail empirical and tail quantile processes based on non-i.i.d. data, e.g. time series and non-stationarity.

At the end of the tutorial, one should be able to use these tools to establish asymptotic theories of new extreme value type estimators developed in their own work.

Tutorial on Statistical Computing on Extremes with R

_______________________________________________________________________

Instructors: Léo Belzile (HEC Montréal) and Thomas Opitz (INRAE Avignon)

Description: This workshop will review R implementations of a variety of techniques in statistical analysis. The focus of the first part of the workshop will be on univariate extremes, including likelihood-based, Bayesian and nonparametric methods for both peaks-over-threshold and block maxima approaches, with a foray into nonstationary extremes. The second part of the workshop will concentrate on conditional extremes and time series. These two sessions will be supported by a recent review paper co-authored by Léo and Thomas.

The Springer journal Extremes has organized a competition for Best Student Paper Award at EVA 2023 in Milan.

The corresponding author of the best paper will be awarded a prize of 500 € sponsored by Springer-Verlag with the option of publishing the paper in Extremes (after a review).
