Release 8.1 of the SCA System is organized into editions designed to meet the needs of users with varying capability requirements and expertise in time series analysis and forecasting applications. Powerful add-ons for GARCH, data mining, predictive modeling, and advanced econometric modeling are provided in the SCAB34S applets and B34S ProSeries Econometric System.
For academic users teaching the fundamentals of time series methods, SCA offers an Educational Edition that encapsulates time-tested capabilities in time series analysis and forecasting. The Educational Edition is regularly priced at $395. We also offer student bundling of SCA software with the book Time Series Analysis and Forecasting at a very affordable price. Depending on course coverage, the SCA Educational Edition or other more advanced SCA Editions may be bundled.
The SCA Practitioner Edition provides expert-system automatic time series modeling and forecasting features with power-packed capabilities to automatically detect and adjust for outliers during estimation and forecasting. It also provides the necessary tools to identify, estimate, diagnostically check, and forecast based on traditional user-directed methods. This edition appeals to users with large-scale forecasting applications as well as users interested in time series data mining and exploration.
For those users with interest in expanded capabilities, we offer Professional Editions of the SCA System that add vector ARIMA and simultaneous transfer function models, causality tests, time-varying parameter models, segmented time series modeling and forecasting, GARCH and other nonlinear modeling, and more. The extensive capabilities included in various editions of the SCA System are best described in the second edition of the book, Time Series Analysis and Forecasting. A copy of the book will be included FREE with a new purchase of the SCA System (Practitioner Edition and above).

SCA's suite of available software products are modularly designed and available across a wide range of computing platforms that encompass more than twenty-five operating systems on PCs, workstations, and mainframes.
SCA software may be integrated into corporate-specific applications such as demand forecasting, inventory control, marketing analysis, and other decision support systems. It may also be used as a standalone statistical application package, providing users with a convenient programmable command language and convenent graphical user interface.
The SCA Statistical System was developed under the advisory direction of distinguished individuals such as George Box, George Tiao, Lon-Mu Liu, and Mervin Muller. Many of the state-of-the art capabilities of the SCA System are made possible through the contributions and counsel of a number of leading researchers in the fields of statistics, econometrics, decision analysis, engineering, and finance.
多年的SSI已經有了廣泛分佈套房四IRT （項目反應理論）稱為BILOG -MG ， MULTILOG ， Parscale和Testfact方案。然而，隨著成長和成功也帶來新的用戶和新的期望。儘管取得了成功，這些IRT程序是遠遠不夠完善以今天的軟件的標準來衡量。此外，它們共享了大量的相似性和重疊的功能的。因此，可以明顯看出一個國家的最先進的單，軟件產品必須開發，以取代這四個程序。
XLSTAT is a Microsoft Excel add-in that has been developed since 1993 to enhance the analytical capabilities of Excel. XLSTAT relies on Excel for the input of data and the display of results, but the computations are done using autonomous software components. The use of Excel as an interface makes XLSTAT a user-friendly and highly efficient software. The quality of the computations is identical to that offered by the leading scientific packages.
