Module summary

In big data with multiple variables, it is vital to discover pattern and infer valuable information from the data. This module introduces basic techniques from multivariate statistics, with the aim to discover, describe and exploit dependencies between variables in complex datasets.

Objectives

To introduce basic techniques from multivariate statistics, with the aim to discover, describe and exploit dependencies between variables in complex datasets.

Learning outcomes
On completion of the module, the student should:
- be able to discover and exploit dependency between variables;
- be able to reduce the dimension of a dataset with dependent components, and interpret the results;
- be able to identify clusters in a given data set;
- be able to visualise similarities between observations in lower dimension.


Syllabus

- Introduction to multivariate analysis
- Statistical dependence, covariance matrix
- High dimensional problems, the "curse of dimensionality"
- Principal Component Analysis (PCA), dimension reduction
- Clustering, K-means method, distances between/within clusters
- Multidimensional Scaling (MDS)

Private study

The student will be expected to complete regular written worksheet assignments testing their understanding of theoretical course elements.

The student will learn to perform analysis using the software package R, which includes performing dimension reduction such as principal component analysis and factor analysis, clustering such as hierarchical and k-means clustering, multi-dimensional scaling, and learning different types of plots for presenting high-dimensional data into informative two-dimensional. Part of the assessment for the module consists of a practical, where the student will apply these techniques to a real-world data set.

Opportunities for Formative Feedback

Monitoring by regular worksheets and achievement in supervised practical sessions.
