STAT3010 Statistical Methods in Insurance

Module Overview

Aims and Objectives

Module Aims

To explain the need for short term insurance contracts and to look at the ways in which insurance contracts are written, including the operation of re-insurance arrangements. To use statistical models to describe methods for determining both premiums and effective re-insurance arrangements. To introduce the use of generalised linear models, machine learning and time series in insurance.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Understand the definitions of some basic insurance terms, particular those relating to short-term contracts
  • Understand the properties of some loss distributions: gamma, exponential, Pareto, generalised Pareto, normal, log-normal, Weibull and Burr, and how to fit them to complete claim size data
  • Understand how simple forms of proportional and excess of loss re-insurance are arranged
  • Model the distribution of the aggregate claims for both the insurer and the re-insurer, particularly using the compound Poisson distribution
  • Use Bayesian approaches to credibility theory to calculate premiums in general insurance
  • Describe and apply basic principles of machine learning
  • Understand the fundamental concepts of generalised linear models and how they may be applied
  • Understand the main concepts underlying the analysis of time series and how to apply them
  • Apply problem solving and numerical skills
