## Information for Part 2 Stochastic Models 2004/05

The Stochastic Models web pages now appear to be working.
All materials can be access from there.
Let me know if you have problems with them.

# Part II Discrete Stochastic Modelling 2003/04

This course, together with next year's course in Continuous Stochastic Modelling,
covers
the material for subject 103 of the
Institute and Faculty of Actuaries'
examination syllabus.

The items I shall be making available from this page will largely
consist of course notes, which in turn will simply consist of
the OHP slides used during lectures.

Many of the files are in pdf format. You will need to obtain Acrobat Reader if you do not
already have it.

General introduction to the course

### Tutorial exercises

### Coursework

Coursework generator is a web page from which you will
be able to print off your own coursework.

Data for coursework 2.

### Notes

- Introduction
- Modelling and Simulation and
Simulation Methods
- Stochastic Processes
- Random Walks
- Markov Chains
- Time-inhomogeneous Markov Chains
- Poisson Processes
- Time Series: Theoretical
- Time Series: Practical

#### Worksheets for lab sessions

- Session 1
- Session 2
- Session 3

DAX data in the form of an Excel file.

#### Past exam questions

Some exam questions set in past years are available for practice. Note that the syllabus
of this course and related courses is constantly changing, so you might encounter some
parts of questions which you are unable to solve.

In addition to these, solutions are provided to the May/June examination papers in
2000,
2001, 2002
and 2003.

Not directly bearing on the syllabus, but maybe of interest anyway, is:
