BAYESIAN INFERENCE FOR DATA SCIENCES - 2022/3
Module code: MAT3052
Module Overview
The module looks at the branch of statistics called Bayesian Statistics. It relies on subjective probability and looks at why this is extremely useful for modelling realistic problems. The module covers an introduction to Bayesian statistics, incorporating prior to posterior analysis for a wide range of statistical models. This shows the students an alternative approach to the Classical statistics that they have studied so far and looks at various statistical techniques that they have studied before and gives them a Bayesian approach.

Assessment Strategy
The assessment strategy is designed to provide students with the opportunity to demonstrate:
- Understanding of and ability to interpret and manipulate mathematical statements.
- Subject knowledge through the recall of key definitions, theorems and their proofs.
- Analytical ability through the solution of unseen problems in the test and exam.
- Ability to implement computational Bayesian method and use visualisation tools to present the result via statistical software such as Python
Thus, the summative assessment for this module consists of:
- One two-hour examination; worth 75% module mark.
- One assessed coursework; worth 25% module mark.
Formative assessment and feedback: Students receive written feedback via marked coursework assignment
Module aims
- Introduce the rationale for, the main techniques of, and general issues in Bayesian statistics
- Apply techniques to standard statistical models such as normal linear models
- Apply Bayesian approaches to estimation and testing
- Introduce Bayesian prediction
- Consider the role of decision theory
- Computational Bayesian technique using Gibbs sampling

Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
- A detailed introduction to the theory behind, methodology and approaches used in Bayesian statistics
- Experience (through demonstration) of the methods used to interpret, understand and solve problems in analysis
The learning and teaching methods include:
- face-to-face seminars and lectures, supported by face-to-face computer lab sessions designed to develop programming skills to apply Bayesian inference to analyse real-world data.
- online recorded material designed to complement the face-to-face sessions.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
