SigmaStat is a statistical software package, which was originally developed by Jandel Scientific Software in the 1980s. As of October 1996, Systat Software is now based in San Jose, California. SigmaStat users have the ability to compare effects among groups. This includes before and after or repeated measure studies. The users can also conduct survival analysis, analyze rates and proportions, perform regression and correlation analysis and calculate power and sample size. The program uses a wizard based interface which asks the user questions about the project and its data. After a test is run, the user receives a detailed report that interprets the results.
If installed with SigmaPlot, SigmaStat integrated with SigmaPlot and SigmaPlot gained advanced statistical analysis capabilities from version 11. SigmaStat is available both as a separate product or is available integrated with SigmaPlot.
On February 1st, 2016 SigmaStat version 4 was relaunched as a separate Advisory Statistics Software by Systat Software Inc.
With SigmaStat version 4 users have multiple new statistical procedures like Principal Components Analysis (PCA), One-Way Analysis of Covariance (ANCOVA) with multiple covariates, Deming Regression and Cox Regression. Users can experience a new user interface which includes the ribbon interface, right-click mouse menus and drag and drop of items in the Notebook Manager. SigmaStat users can now access 36 new probability distribution functions added to the transform language and generalized weighting added to nonlinear regression which allows use of user determined error distributions and to enable robust fitting techniques. It also has profile plots for multi-factor ANOVA and normality test graphs. A new graph properties dialog box makes editing graphs much easier with instant redraw when properties are changed.
