This course is about the statistical modelling of time series data. The course focuses on the three main areas; (i) modelling trends and seasonal patterns; (ii) modelling short-term correlation; and (iii) predicting observations at future points in time.
Practicals: 2, 2-hour computer lab sessions
Requirements of Entry
The normal requirement is that students should have been admitted to an Honours- or Master's-level programme in Statistics.

Main Assessment In: April/May
Are reassessment opportunities available for all summative assessments? Not applicable
Reassessments are normally available for all courses, except those which contribute to the Honours classification. For non Honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions for this course are described below.
To introduce the concept of a time series, and discuss a range of descriptive methods for identifying features of interest;
To present a range of approaches for representing trends and seasonality in a time series, and to assess their relative merits;
To describe the theoretical properties of commonly used time series models;
To describe a range of approaches for predicting future values of a time series;
To show how to apply the techniques from the course to real time series data sets in the statistical package R.
Intended Learning Outcomes of Course
By the end of this course students will be able to:
■ determine whether a time series exhibits any evidence of a trend, seasonality or short-term correlation;
■ define what it means for a time series to be stationary;
■ define the class of ARIMA probability models;
■ determine whether a particular model from the class of ARIMA models is stationary and invertible;
■ derive the mean, variance and autocorrelation function for a particular model from the class of ARIMA models;
■ determine an appropriate model for a data set from the class of ARIMA models;
■ predict future values for a given time series;
■ use the statistical package R to fit an appropriate time series model to a real data set that adequately captures any trend, seasonality and short-term correlation in the data;
■ have basic understanding of intervention models for time series with abrupt changes in behaviour
