Aims & Learning Objectives:
Aims:
To develop skills in the analysis of multivariate data and study the related theory.
Objectives:
Be able to carry out a preliminary analysis of multivariate data and select and apply an appropriate technique to look for structure in such data or achieve dimensionality reduction. Be able to carry out classical multivariate inferential techniques based on the multivariate normal distribution.
