The (non-digital) oral exam is supposed to be on Friday, 26. May and 30. May, 2023 (starting at 9:00 am), that is

26. May, Friday: 09:00-15:00 (5 students)

and 

30. May, Tuesday: 09.00-13:00 (4 students)

Please, let me know (via email) which exam day you prefer!

Place and time will be announced, soon.

The exam procedure is as follows: The exam takes 45 min. and consists of two parts:

1. Talk/presentation of a topic of free choice about extreme value statistics. The title and topic of the presentation are supposed to be communicated to me (by e-mail) latest 3 days (!) before the exam and approved by myself. The length of the talk is limited to 20 minutes and the form of the presentation is up to the candidate (blackboard, beamer slides,...).

2. General questions about extreme value statistics.

We are supposed to have an oral exam for STK4550!

The date for the oral exam is not fixed yet and will be discussed with the students.

In our last lessons (21. Feb.-15. March) we studied the exact asymptotics of ruin probabilities in the case of large claim sizes, by using e.g. mathematical tools from the theory of regularly varying functions. See Chapter 1 in the book of Embrechts.

Then, we continued with the discussion one of the main results of extreme value theory, that is the theorem of Fisher-Tippett-Gnedenko, which can be regarded as a central limit theorem for maximal claims (Ch. 3 in Embrechts). The latter result is also important for the practical study of large claims, which may cause the spontaneous ruin of an insurance company.

In addition, we have addressed the problem of the characterization of the maximum domain of attraction of extreme value distributions.

Our study plan for the next weeks is the following:

Vi startet opp kurset v?rt med en kort innf?ring i ekstremverdistatistikk og teori av store avvik og skaffet oss oversikt over emner vi kommer til ? studere. Dessuten repeterte vi (25./31. jan.) grunnleggende begrep og resultater fra sannsynlighetsregning (f.eks. stokastisk prosess, (betinget) forventningsverdi,...) som vi f.eks. trenger til estimering av ekstremverdi-fordelinger.

Etter vi har studert effektene av "sm?" forsikringskrav p? modeller fra risikoteori (kap. 1 i boken til Embrechts), kommer vi til ? gj?re det samme for "store" krav neste gang (21. feb.).

 

In our first lesson I gave a brief introduction to extreme value theory and the theory of large deviations and an overview of some central problems we want to study in this course. Further, in our last lessons (25./31. Jan.) we finished our crash course on basic concepts and results from probab...
