Module aims

This module is to introduce a variety of statistical models for time series and cover the main methods for analysing these models. In this module students continue to develop their modelling-for-inference skills. Students learn to appreciate the difference between data indexed by time vs. cross-sectional data and the need for special exploratory and inferential techniques. This module should enrich the already acquired battery of statistical models to tackle the exploration and information extraction from real-life data with a mixture of theory and practice.

Students who wish to take this module should consider taking Stochastic Processes MAT00030H in Autumn Term, although this is not a formal pre-requisite.

The module Statistics Option (MAT00033I) can be used as a pre-requisite in place of Probability and Statistics MAT00035I if necessary.

Module learning outcomes

At the end of the course, the student should be able to define and apply the main concepts underlying the analysis of time series models. Starting with the different aspects of the concept of stationarity and exploration of real data through to fitting ARIMA models and producing forecasts. Students should also be acquainted with the concept of non-stationarity and transformations of data to stationarity. Specifically, the students should be able to:

  • Compute and interpret a correlogram and a sample spectrum
  • Derive the properties of ARIMA models
  • Choose an appropriate ARIMA model for a given set of data and fit the model using an appropriate package
  • Compute forecasts for a variety of linear models.
