# MATH6157 Applied Statistical Modelling

## Module Overview

This module will introduce important general aspects of statistical modelling and some fundamental aspects of data collection for computer and simulation experiments. A broad range of commonly-used statistical models will be encountered, and used to demonstrate both general principles and specific examples of modelling techniques in R and, briefly, Python. A variety of exemplar applications and data sets will be presented.

### Aims and Objectives

#### Module Aims

To introduce, via a hands-on approach, the basic concepts and principals in statistical modelling in a computational paradigm.

#### Learning Outcomes

##### Learning Outcomes

Having successfully completed this module you will be able to:

• After taking this module, students should understand - why statistical modelling is important
• After taking this module, students should understand - how to use R to fit, explore and exploit a variety of statistical models
• Demonstrate an ability to concisely convey technical results
• After taking this module, students should understand the terminology and statistical principles associated with modelling
• After taking this module, students should understand sufficient theory to deal with simple examples and have gained practical hands-on experience in more complex examples
