Remember (!)  to inform me about the topic of your presentation latest 3 days before the exam (i.e. on Tuesday, 24. May)!

The (non-digital!) oral exam is supposed to be on Friday, 27. May, 2022 (starting at 9:00 am), that is

27. May, Friday: 09:00-16:00 (6 students, 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. 

The pensum of the course comprises the sections 1, 2, 3, 4, 5 in my lecture notes.

Regarding section 5 (Weak convergence of point processes) knowledge about basic notions is assumed (i.e. d...

The Department of Mathematics at the University of Oslo has again the pleasure to invite you to an Insurance Day! We offer a schedule with interesting topics within finance and insurance. This event brings industry and academia together and it is also a good chance for students to come in touch with our industrial partners! Among other topics we have:

-          Reserving models and the use of new technology,
-          Market valuation in life insurance,
-          Expected longevity and pensions,

In our last lessons (8. Feb.-1. March) we studied the exact asymptotics of ruin probabilities in the case of small and large claim sizes, by using Smith?s key renewal theorem and the theory of regularly varying functions. See Chapter 1 in the book of Embrechts.

Further (2.-9. March) we discussed 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.

Next time (15./16. March) we want to address 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:

End of March: Discussion of convergence rates with respect to the Fisher-Tippett-Gnedenko theorem and s...

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 (27. jan./2. feb.) grunnleggende begrep og resultater fra sannsynlighetsregning (f.eks. stokastisk prosess, (betinget) forventningsverdi,...) som vi f.eks. trenger til estimering av ekstremverdi-fordelinger.

Neste gang (8. feb.) skal vi fortsette med kap. 1 i boken til Embrechts og studere effektene av "sm?" og "store" forsikringskrav p? modeller fra risikoteori. 

 

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 (27. Jan./1. Feb.) we finished our crash course on basic concepts and results from&nb...

From next week on, there will be on-campus teaching at the Department of Mathematics.

  • We encourage the students to follow normal infection control measures during the lectures, i.e. distance, mask, absence in case of respiratory infections
  • There will be a digital alternative to the ordinary teaching, at least a scanned version of lecture notes that are posted on the semester page 
  • Details about exam will be presented later

Prof. Colin Ramsay (University of Nebraska-Lincoln) will give a mini course on "Pension Mathematics for Single Employer Defined Benefit (DB) Plans" in February (01.02.22-24.02.22). The course is strongly recommended to master and bachelor students in insurance and financial mathematics. Some background knowledge on insurance mathematics (based e.g. on STK3505) would be desirable for this course.

See the file for a more detailed course description.

Time: Every Tuesday, 10:15-12:00 in the time period 01.02.2022-22.02.2022

          Every Thursday,10:15-12:00 in the time period 03.02.2022-24.02.2022

Place: room 1000, NHA.

You are welcome to this course!
