Reapplying a Time Series Model

This example applies the time series models from the first time series example but can also be used independently. See the topic Forecasting with the Time Series Node for more information.

As in the original scenario, an analyst for a national broadband provider is required to produce monthly forecasts of user subscriptions for each of a number of local markets, in order to predict bandwidth requirements. You have already used the Expert Modeler to create models and to forecast three months into the future.

Your data warehouse has now been updated with the actual data for the original forecast period, so you would like to use that data to extend the forecast horizon by another three months.

This example uses the stream named broadband_apply_models.str, which references the data file named broadband_2.sav. These files are available from the Demos folder of any IBM® SPSS® Modeler installation. This can be accessed from the IBM SPSS Modeler program group on the Windows Start menu. The broadband_apply_models.str file is in the streams folder.
