To begin a time series analysis, choose the Time Series
command from the Analyze > Modeling
submenu to display the Time Series Launch dialog (Figure 9.1
). This dialog allows you to specify the number of lags to use in computing the autocorrelations and partial autocorrelations. It also lets you specify the number of future periods to forecast using each model fitted to the data. After you select analysis variables and click OK
on this dialog, a platform launches with plots and accompanying text reports for each of the time series (Y
) variables you specified.
