How to Cite SYSTAT Used in Research Papers and Publications
Since SYSTAT is a very well established scientific software product, one would only need to cite “SYSTAT Version 13″ in the materials used or methods section of your paper.
Another and more simple way is to reference SYSTAT without listing its version number , would look like this:
SYSTAT (Systat Software, San Jose, CA)
If you used one of the curve fitting functions within SYSTAT you might cite:
“The data was fit with a modified three parameter exponential decay using SYSTAT version 13, from Systat Software, Inc., San Jose California USA, www.sigmaplot.com “.
