About the module

Topics covered

The MATH20802 module is designed to run over the course of 11 weeks. It has three parts:

  1. Likelihood estimation and likelihood ratio tests (W1–W5)
  2. Bayesian learning and inference (W6–W8)
  3. Linear regression (W9–W11)

This module focuses on conceptual understanding and methods, not on theory, As such, the presentation in this course is non-technical. The aim is to offer insights how diverse statistical approaches are linked and to demonstrate that statistics offers a concise and coherent theory of information rather than being an adhoc collection of “recipes” for data analysis (a common but wrong perception of statistics).

Prerequisites

For this module it is important that you refresh your knowledge in:

  • Introduction to statistics
  • Probability
  • R data analysis and programming

In addition you will need to know matrix algebra and how to compute the gradient and the curvature of a function of several variables.

Check the Appendix for a brief refresher of the essential material.

Additional support material

Accompanying these notes are

Furthermore, there is also an MATH20802 online reading list hosted by the University of Manchester library.

If you are a University of Manchester student and enrolled in this module you will find on Blackboard:

  • a weekly learning plan for an 11 week study period,
  • weekly worksheets with examples and solutions and R code, and
  • exam papers of previous years.
