EASI/ARIMA - The 2% Solution is as the name implies is easy to use, and it does, in fact, provide forecasts within a mean error of 2%. Many of the price forecasts I ran were less than 1% error. In a nutshell, my overall impression is that the package is excellent and represents good value in its effortless use to provide meaningful forecasts from a broad spectrum of readily available database formats. Additionally, the ARIMA technique is not limited to price forecasting and may be used to forecast sales, chemical viscosities, airline miles flown, or any other time series.
I had the opportunity to test the latest Apple Version 3.0. (A similar software version is available for the IBM PC. This is furnished in compiled BASIC which runs two to three times faster than the Apple.) From the moment I opened the package, I underwent an enjoyable experience. The Apple EASI/ARIMA comes with a manual, a primer, a utility disk, and program disk. Both diskettes are copyable so backup copies are never a problem. The primer is specific to the user's requirements and is intended to bridge the gap between the computer output and its usage. In this case the futures version provides examples of the output and some pointers on how the author would use the forecasts in real life situations by "walking through" three examples of DMarks, Gold, and Wheat Futures. Sample databases are supplied so that the material in the primer can be duplicated. The primer was written by a man in tune to speculative markets and provides sufficient working knowledge without the necessity of a sophisticated statistical background.
