Module G1101
Module details for 2022/23.
15 credits
FHEQ Level 6
Module Outline
Rationalisation:
After the introduction of the Poisson process, birth and death processes as well as epidemics models can be presented in full generality as applications of the pooled Poisson process. At the same time, the students will be introduced to the Kolmogorov equations and to the techniques for solving them. Renewal theory is needed to better understand queues, and, for this reason, it is discussed before queues.
Modernisation:
A modern introductory course on stochastic processes must include at least a section on compound renewal processes (with a focus on the compound Poisson process) as well as a chapter on the Wiener process and on Ito stochastic calculus. This is necessary given the importance this process has in several applications from finance to physics. Modernisation is achieved by including a new introductory chapter divided into three parts.
1. Poisson processes:
a. Density and distribution of inter-event time.
b. Pooled Poisson process.
c. Breaking down a Poisson process.
d. Applications of the Poisson process, e.g. birth-and-death processes, the Kolmogorov equations.
2. Renewal processes:
a. The ordinary renewal process.
b. The equilibrium renewal process.
c. The compound renewal process.
d. Applications of renewal processes, queues.
3. Wiener process:
a. Definition and properties
b. Introduction to stochastic integrals
c. Introduction to stochastic differential equations.
Module learning outcomes

Please note that the University will use all reasonable endeavours to deliver courses and modules in accordance with the descriptions set out here. However, the University keeps its courses and modules under review with the aim of enhancing quality. Some changes may therefore be made to the form or content of courses or modules shown as part of the normal process of curriculum management.
The University reserves the right to make changes to the contents or methods of delivery of, or to discontinue, merge or combine modules, if such action is reasonably considered necessary by the University. If there are not sufficient student numbers to make a module viable, the University reserves the right to cancel such a module. If the University withdraws or discontinues a module, it will use its reasonable endeavours to provide a suitable alternative module.
