# ST221 - Linear Statistical Modelling

• Module code: ST221
• Module name: Linear Statistical Modelling
• Department: Statistics
• Credit: 12

## Module content and teaching

###### Principal aims

To introduce the ideas and methods of statistical modelling and statistical model exploration. To introduce students to the application of R software and its use as a tool for statistical modelling, specifically for working with linear models in a variety of different scenarios.

###### Principal learning outcomes

1. Introduction to the R software. Some useful methods of examining large data sets. The use of this package to obtain important summary features in different data structures. 2. A review of the simple linear regression. Distributions of estimators and residuals. 3. An introduction to mutiple regression. Estimators of these models. How the study of residuals can inform and refine model choice. How to use R to check the plausibility of such a statistical model and how to use diagnostic plots in combination with the theory of model refinement. 4. Introduction of polynomial regression and various ANOVA models. The coding and interpretation of these models using R. 5. An introduction to linear models for time series and generalized linear models for frequency data.

###### Timetabled teaching activities

3 lectures/week, 4 hours of computer practicals. This module runs in Term 2/3.
