The WA Branch of the Statistical Society of Australia warmly invites you to a workshop on Nonstationary Time Series: Techniques and Tools, presented by Professor Guy Nason of Imperial College London, the Frank Hansford-Miller Fellow for 2023.
Date: Thursday, 27 April 2023.
Time: 9:00AM - 5:00PM.
Location: Curtin 139 St Georges Terrace, 139 St Georges Tce, Perth, WA.

Abstract
This workshop covers the modelling and analysis of (second-order) nonstationary time series. That is, time series whose second-order properties (variance, autocovariance) can change over time. We will look at some models for nonstationary time series and study their controlling parameters. We will then examine methods for estimating those parameters and statistical tests that can be used to detect non-stationarity in such time series. In the second part we will look at methods for estimating local versions of the classical autocovariance and partial autocovariance, which can provide a lot of insight into the behaviour of the series over time. Finally, we will examine methods and software for forecasting such series and seeing how they compare to methods designed for stationary series. If time permits, we might examine some network time series models.
Prerequisites
Laptop with R installed. Attendees will be using the
locits,
lpacf and
forecastLSW packages. The latter two packages will be available on CRAN shortly.

About the Presenter
Professor Nason is Chair in Statistics at Imperial College London. He has undertaken research in the areas of wavelets and time series analysis, particularly in the area of non-stationary time series. A major current research direction is network time series in which he is involved in the NeSTProgramme Grant - a partnership of nine investigators at the six UK universities of Bath, Bristol, LSE, Oxford, York and Imperial.
Registration Information
This workshop will be conducted as an in-person event only. The registration fee includes morning and afternoon tea.
