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

Information about important academic dates including deadlines for withdrawing from units are available at https://www.mq.edu.au/study/calendar-of-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
  • Demonstrate knowledge of the limitations of such modelling
  • Demonstrate knowledge of the theoretical issues, including asymptotic behaviour of parameter estimators
  • Be able to write Matlab code to implement the algorithms developed in the course

General Assessment Information

Assignments may be handwritten, and submitted in person, or electronically via email to Prof Quinn. There is no requirement that assignments be word-processed, since the mathematical typesetting capabilities of Microsoft word are inadequate.

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 Statistics Department webpage for details of consultation hours. 

Technologies used and required

Lecture material will be placed on iLearn. If the lecture room is equipped with Echo facilities, they will be used, i.e. audio and/or video recordings will be available soon after the lecture.

Students will need to use a computer for most of the assessments. There will be extensive use of Matlab during practical classes. Students are entitled to download the full version of Matlab, and use it for the duration of their studies. Details are at

https://web.science.mq.edu.au/it/matlab/

I urge you to install it on your laptop, or home desktop. Please email me if you have difficulty, as the download is rather large.
