An Actuary is charged with assessing the uncertainties involved in providing insurance. The quantification of these uncertainties requires statistical methods with some mathematical development. This course investigates modern actuarial modelling and examines the basic techniques used in actuarial analysis. The aim is to provide students with a firm mathematical and statistical background so that they can apply mathematical and statistical models to assess risk factors and apply stochastic models appropriate to the representation of the risk process. By doing so, the students can analyse and solve practical problems in actuarial sciences.

Learning outcomes

On successful completion of this course a student will be able to:

1. recognize the basic concepts and standard terms in actuarial science.
2. apply the typical long-tailed distributions representing claim size and those representing claim number, use appropriate methods to extract relevant moment information, and derive consequential information about total claim size.
3. use life tables, determine and manipulate the financial functions relating to life insurance.
4. apply appropriate mathematical methods in actuarial calculations and obtain solutions for some problems in risk theory.
5. make effective use of statistical models to analyse the risk factors for categories of policy holders.
6. critically appraise the results of your analysis, and appreciate disciplines and forms of professional practice beyond Actuarial science, and draw connections between them.

Indicative content
