Unit description Unit description
This unit is an introduction to the statistical theory and practice of Time Series Analysis. A Time Series is a set of data indexed by time. A time series is modelled as a single 'realisation' or sample of a stochastic process, i.e. a collection of (possibly) dependent random variables. The unit looks at suitable models for time series, examines the estimation of parameters in these models, hypothesis testing (and alternatively estimating the number of parameters), prediction of future values of the time series (forecasting), models for multivariate time series and the estimation of periodicity. There will also be a limited look at modelling stochastic volatility. Emphasis in this unit will be on practice.

Important Academic Dates

Learning Outcomes

On successful completion of this unit, you will be able to:

  • Be able to model real time series using a variety of techniques
  • Be able to judge the adequacy of these models
  • Be able to use these models to forecast future values
  • Have seen many of the theoretical issues, including asymptotic behaviour of parameter estimators
  • Know the limitations of such modelling
  • Be able to write Matlab code to implement the algorithms developed in the course

General Assessment Information

Students MUST perform satisfactorily in the final examination in order to pass the unit regardless of their performance throughout the semester. Students should note that, if they fail the final examination, their coursework will not count and the SNG allocated will be based on their final examination mark only.

The only exception to not sitting an examination on the designated date is because of documented illness or unavoidable disruption. In these circumstances you may wish to consider applying for special consideration.

Assignment 1

Due: 26 August
Weighting: 10%

Assignments may be submitted electronically, via email to Prof Quinn, but NOT via iLearn. There is no requirement that assignments be word-processed, since the mathematical typesetting capabilities of Microsoft word are inadequate (The lecture notes have been prepared using LaTeX).

Delivery and Resources

There are three contact hours per week, usually comprised of two hours of lectures and one hour of practical work. Check the timetable for classes.

Please consult iLearn or the Unit webpage for details of consultation hours.

Grading in this unit

Your final SNG and grade in STAT722 will be based on your work during semester and in the final examination as specified in the ‘Assessment’ section. The determination of your final SNG and Grade will be based on an assessment of your performance on individual assessment tasks against identified criteria and standards as set out in the section titled ‘Assessment Criteria’, and an assessment of overall performance in the unit. Final grades will be awarded on the basis of your overall performance and the extent to which you demonstrate fulfilment of the learning outcomes listed for this unit.

The relationship between SNGs and Final Grades is shown in the table below:

The lecture notes are extensive.

Matlab version 2013b or 2014a  will be used in the practical classes. It is not possible to give students copies of this version, but an older version is available free from the lecturer. Although this version is old, it is the last version which students are freely permitted to install on their own computers. Students may also use iLab, which requires internet access. Students using Windows 8 will need to use a special vmware edition of the old Matlab version.
