MathSoft has licensed this language and assembled it into a graphically oriented program fully integrated into the Windows environment. The standard InstallShield Wizard program that comes with new Windows 95 and Windows NT software has taken the challenge out of installing software. So long as your PC has sufficient disk space, RAM and available swap file space, all you have to do is click a button and watch the software install itself. Of particular interest is the Trellis graphics feature. Graphic output can be converted into a PowerPoint presentation.
All graphs are objects so that each feature can be edited using a built-in graphics editor.
The object orientation extends to the data analysis and output, with each procedure stored as a working model whose components can be referenced specifically. However, the robust regression feature is particularly noteworthy. A scripting window is available for programmers to create their own functions and procedures, and to modify and customize the graphical environment. Garch is particularly useful in modeling time series, such as volatility, where levels surge from state to state and then persist there for some time. All classes of Garch models, including multivariate, are included.
