GENERAL LINEAR MODELS - 2021/2
Module code: MAT2002
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module introduces least squares fitting, methods of inference based on normal theory, diagnostics and analysis of data from simple designs.

Number of Credits: 15
ECTS Credits: 7.5
Framework: FHEQ Level 5
JACs code: G100
Module cap (Maximum number of students): N/A
Prerequisites / Co-requisites
MAT1033 Probability and Statistics
Indicative content includes:
- Review of one and two sample normal-based methods
- revision of R and further use of R
- Covariance and correlation
- The simple linear regression model – least squares estimation, prediction
- Multiple regression and selection of variables
- Completely randomised and randomised block experiments – one-way and two-way analyses with interaction
- General regression approach to analysis, residual analysis and diagnostics
|Assessment type||Unit of assessment||Weighting|
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 coursework, test and exam.
Thus, the summative assessment for this module consists of:
· One two hour examination at the end of the Semester; worth 80% module mark.
· One Coursework, worth 20% module mark.
Formative assessment and feedback
Students receive written feedback via marked coursework assignment over an 11 week period. In addition, verbal feedback is provided by lecturer at practicals.
- Introduce basic concepts of statistical modelling
- study model fitting and selection for simple linear regression, polynomial regression and multiple regression models
- consider and analyse simple experimental design models
- use linear models in prediction and problems that may arise
- use of R to apply theory to practical data analysis, using data from various areas of business and economics, science and industry

Overall student workload
Independent Study Hours: 117
Lecture Hours: 23
Seminar Hours: 10
Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
A detailed introduction to the theory behind linear models using least squares estimation
Experience (through data analysis and R practicals) of the methods used to interpret, understand and solve problems in analysis
The learning and teaching methods include:
- 3 x 1 hour lecture the first week and then 2 x 1 hour lectures per week x 10 weeks, with additional notes on white board to supplement the module handbook and Q + A opportunities for students
- 1 x 1 hour practical session using R per week x 10 weeks to analyse data using the techniques learnt with lecturer/tutor walking around to support learning.
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.
