Extreme Value Theory with Implementation in S-PLUS
Extreme value theory has been subject of much practical and
theoretical work in the last few years. Recent developments have
introduced very flexible and theoretically well motivated
semi-parametric models for extreme values which now are at the stage
where they can be used to address important technological problems on
handling risks in areas such as wind engineering, hydrology, flood monitoring and prediction, climatic changes,
structural reliability, corrosion modelling, and large insurance
claims or large fluctuations in financial data (volatility).
This course is mainly for mathematical statistics graduate students
and will give an overview of a number of different topics in modern
extreme value thoery (of course interested faculty are always
welcome). These topics will include the following:
- Univariate extreme value theory
- Threshold models
- Point process characterization of extremes
- Multivariate extremes
- Statistical methods for extremal events
The objective of the course is two-folded. Firstly, we intend to cover
the probability theory of univariate and multivariate extreme value
theory in the case of independent variables. Our approach will be
mainly from applied point of view so statistical modeling of extreme
events will be main emphasis of the course. As a modeling language we
will be using S-PLUS so the secondary goal of the course is
that, upon
completing
the course, participants will be able to use and write programs in
S-PLUS for their own applications. To this end
we will discuss a
few examples of applications of the extreme value theory in
S-PLUS in details. These example are mainly taken from a few
papers which have recently been published and we will go through
the details of calculations which are behind the results presented
in the papers.
We will als cover the fundamentals of S-PLUS which are
necessary for statistical modeling in general. This will include:
- Overview of S-PLUS
- Data Objects in S-PLUS
- Data Import and Export, Manipulation and Restructuring
- Graphics
- Functions and Operators
- Writing Functions
- Optimization routines in S-PLUS
The course will meet two times a week (2x45 each time) for the first reading
period and perhaps part of the second reading period. At the time, the
preliminary plan of the course is that each part of the course
will take up about half of the lectures. Each lecture will
concentrate only either in extreme value theory or S-PLUS
programming so participants who wish
to follow only one part of the course will be able to attend only
those
lectures which are of interest to them.
The course will give 8 graduate points (5p for extreme values and 3p for S-PLUS).
Literature
During the course we will use material presented in various
papers. I will try to hand out in advance copies of the papers to
those participants who follow extreme value part of the course. The
