This opens the Exponential Smoothing dialog box. As in Chapter 4, move score into the
Variables list. Leaving the model set at Simple, click Parameters and request a grid
search for alpha. Click Continue to return to the main Exponential Smoothing dialog
box, and click Save. From the Create Variables group, select Do not create, since the
purpose here is not to create a smoothed series.
Click Continue again, and then click OK to carry out the exponential smoothing. The
results are shown in Figure 6.2.
