STAT6075 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, decision theory 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, particularly those relating to short-term contracts
  • Understand the main concepts underlying the analysis of time series and how to apply them
  • Use Monte Carlo simulation to estimate quantities of interest in models used for insurance
  • Apply problem solving and numerical skills
  • 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
  • Understand the concept of ruin in a risk model
  • Apply techniques for analysing run-off triangles and projecting the ultimate position.
  • Use Bayesian approaches to credibility theory to calculate premiums in general insurance
  • Demonstrate knowledge and understanding of the concepts of decision theory and how to apply them
  • Demonstrate knowledge and understanding of the fundamental concepts of generalised linear models and how they may be applied


Review of distribution theory; loss distributions; risk models – collective and individual; re-insurance; ruin theory; run-off triangles; Bayesian credibility theory; decision theory; generalised linear models; time series; random number generation and Monte Carlo simulation.
