Present the concepts and methods of multivariate analysis, emphasizing the applications and attempting to make the mathematics as palatable as possible.
 
The student is expected to:
- Apply linear algebra in variance, covariance and correlation structures and understand geometrical equivalents of basic multivariate reasoning
- Understand properties and applications of the Multivariate Normal distribution
- Carry out inference about multivariate means
- Understand and apply basic ordination, discrimination and classification methodologies: Principal Components Analysis, Factor Analysis, Discriminant Analysis and Cluster Analysis
- Be able to apply these methods on real datasets
- Make use of existing software packages to solve problems in Multivariate Analysis

Calculus, Linear algebra, introductory statistics, linear models.

Type : Partial or continuous assessment with (final) exam during the examination period
Description of evaluation : Written, Paper/Project, Take-Home
Type of questions : Open questions
Learning material : Course material


Examination (open book):

  • 4 questions 
  • 1 question about the paper

The paper counts for 1/4 of the final score for the course.

Students who did not obtain a sufficient score for the paper, need to retake the paper during the third examination period.

In case students obtained a sufficient score for the paper in the first examination period, this score will be maintained in the third examination period.
