The second is to download and install a free copy of StatWizards' Forecast Wizard. The installation will place a number of the duo's lectures and papers on your computer and establish convenient links to them. Follow the instructions for installing the Wizard, then run it within a blank Excel spreadsheet. You will see the opening dialog box for the Wizard.
At any step in the Wizard where an academic paper on the topic at hand exists, the button with the mortarboard and diploma icon becomes enabled; clicking it displays the paper in Adobe Reader. Where a tutorial in Microsoft PowerPoint exists, the icon with the projection screen becomes enabled; clicking that opens a tutorial, also in Adobe Reader. At this point in time, only some of our products contain this feature, but over time all will.
