# Multivariate Statistical Analysis

#### Lecturers

Dr Sharon Lee, The University of Adelaide

#### Synopsis

Multidimensional data arise frequently in many fields of scientific research, from engineering, computer science, finance, medicine, to social sciences. Multivariate statistics provide powerful and flexible tools to extract meaningful information from these data.

This course provides an introduction to various classical statistical methods for analyzing multivariate data, including multivariate extensions of univariate techniques and other tools that are specific for multidimensional data. Students will gain a conceptual understanding and the mathematical underpinnings of the procedures, and be able to applied these to datasets using R.

#### Course Overview

• Introduction to multivariate data, distributions, and analysis
• Inference about multivariate means and regression
• Inference for a single population
• Comparison of multiple populations
• Multivariate regression
• Analysis of a covariance structure
• Principal component analysis
• Factor analysis
• Canonical correlation analysis
• Clustering, classification, and grouping
• Discriminant analysis
• Hierarchical clustering
• k-means and mixture models
• Multidimensional scaling
• Correspondence analysis

#### Prerequisites

• working knowledge of second year probability and statistics (distribution theory, hypothesis testing, ANOVA, linear regression)
• basic multivariate calculus
• familiarity with the R software

#### Assessment

• 2 assignments: 20% each
• 2 quizzes: 10% each
• Final exam (3hr online examination): 40%

#### Resources/pre-reading (if available)

Lecture notes will be provided during the course.
