Stat::Fit® Version 3
Distribution Fitting Software

Stat::Fit ® statistically fits to your data the most useful analytical distribution. Its operation is intuitive, yet its help file extensive. The Auto::Fit function automatically fits continuous distributions, provides relative comparisons between distribution types, and an absolute measure of each distribution's acceptability. The Export function translates the fitted distribution into specific forms for simulation software. Features include descriptive statistics, parameter estimates, goodness of fit tests, graphical analysis, random variate generation, export to simulation products, and more. Up to 50,000 data points.

Distribution Viewer

Visualize your results with our software. Stat::Fit® includes a distribution viewer which provides visualization of the process as well as distribution shaping for the situation where little data exists.

Commercial Updates

If you received Stat::Fit with another product, such as ProModel, ProcessModel, ExtendSim, or Simul8, please contact their customer support desk for any updates or support issues. The current commercial product is an upgrade from previous versions, but is not tied to the other products.
