Detailed study of multivariate methods. Application of multivariate methods, test statistics and distributions.

STAT315 and STAT463 are courses in data modelling. The emphasis is on real world examples, and how you can use models to understand patterns and relationships in data. Multivariable statistical methods are used to extract information from data where there are multiple variables measured, for example in biology, health, engineering, finance, economics, and marketing.

In the course we will cover the application of common statistical methods used to fit models to data including multiple regression and dimension reduction methods like principal component analysis, factor analysis and clustering methods, generalised linear models (GLMs), mixed models (LMM and GLMM), generalised additive models (GAMs), and multiple comparison tests.

The course will introduce and use the statistical analysis software R, which is a powerful tool when dealing with large multivariate datasets. Special attention will be given to practical applications and the interpretation of the results.

Learning Outcomes

  • Students from the courses STAT315 and STAT463 will be able to:

  •            choose appropriate method when analysing data
  •            define the problem in a statistical framework
  •            fit a multivariable regression model to data and interpret the results
  •            understand and apply other dimension reduction methods such as principle component analysis (PCA), factor analysis (FA) and clustering
  •            use a generalised linear model (GLM) with data that does not follow a normal distribution
  •            identify when a mixed-model should be used and apply this to linear and generalised linear models
  •            use a generalised additive model (GAM) with non-linear data
  •            undertake appropriate statistical tests when multiple comparisons are used
  •            use the statistical analysis software R
  •            write scientific and technical reports
