ST402 Risk Theory

Throughout the 2021-22 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and on-campus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information. You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

All dates for assessments for Statistics modules, including coursework and examinations, can be found in the Statistics Assessment Handbook at http://go.warwick.ac.uk/STassessmenthandbook

Introductory description

This module runs in Term 2 and is available for students on a course where it is a listed option. It is not available as an Unusual Option to students with their home department outside Statistics.

Prerequisites:
Integrated Masters: ST318 Probability Theory
MSc: ST903 Statistical Methods

Results from this module may be partly used to determine exemption eligibility in the Institute and Faculty of Actuaries module CM2. (Independent application with the IFoA may be required to receive the exemption.)

Module aims

This module partly fulfils the aim of the MMORSE stream in Actuarial and Financial Mathematics to enable students to study more deeply the area named in the stream. It will cover material of use in general insurance such as loss distributions, ruin problems in compound Poisson processes and credibility theory.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Decision theory.
Loss distributions: standard examples. Excesses and retention limits.
Bayesian Statistics.
Ruin problem in compound Poisson processes; the adjustment coefficient and
Lundberg's inequality.
Credibility theory: Bayes and empirical Bayes approaches.
Run-off triangles: projection of future development; chain ladder method.
Use of GLMs in general insurance.
Time Series.
Simulation of a Stochastic Process.

Learning outcomes

By the end of the module, students should be able to:

  • Know how probability models are used in general insurance
  • Understand the concept of methods of re-insurance to hedge against risk.
