Study-unit Aims:

The main aim of this study-unit is that of familiarizing the students with the theoretical and practical framework underlying the analysis of any data set that involves more than one variable.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will:
- Be able to understand the role that the multivariate normal distribution plays in estimation and hypothesis testing of mean vectors and variance covariance matrices in a multivariate setting;
- Be familiar with various techniques that may be used in multivariate hypothesis testing, with special consideration being given to the likelihood ratio test;
- Have developed a sound background in multivariate estimation theory;
- Have a better appreciation of the role which matrix algebra plays, particularly in analysing covariance structures.

2. Skills:

By the end of the study-unit the student will be able to:
- Use their theoretical knowledge and various statistical packages to perform simulations and to analyse real multivariate data;
- Use the material learnt to understand the theoretical and practical importance of multivariate techniques which have not been covered in this study-unit.
