Extensive Definition

SYSTAT is a statistics and statistical graphics software package, developed by Leland Wilkinson in the late 1970's, who was at the time an assistant professor of psychology at the University of Illinois at Chicago. Systat was incorporated in 1983 and grew to over 50 employees.
In 1995 SYSTAT was sold to SPSS, who marketed the product to a scientific audience under the SPSS Science division. By 2002, SPSS had changed its focus to business analytics and decided to sell SYSTAT to Cranes Software in Bangalore, India. Cranes formed Systat Software, Inc. to market and distribute SYSTAT in the US, and a number of other divisions for global distribution. The headquarters are in San Jose (California).
By 2005, SYSTAT was in its eleventh version having a revamped codebase completely changed from Fortran into C++. Version 12 came out in early 2007, with improvements in the user interface and several new features.
It also produces a software package called SigmaStat that does statistical analysis and performs these tasks using a wizard interface.
