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. 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

Having successfully completed this module you will be able to:

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