drawn up. It considers two alternative approaches to the issue of identifying are models - the Box Jenkins
approach and the objective penalty function methods. The emphasis is on forecast performance which
suggests more focus on minimising out-of-sample forecast errors than on maximising in-sample
‘goodness of fit’. Practical issues in are time series model that, forecasting are illustrated with reference to
