Advanced Distribution Fitting Software for Simulation

Stat::Fit® is a powerful statistical analysis tool designed to help simulation professionals identify the most appropriate probability distributions for their data. It is designed to statistically fit raw data to the most appropriate probability distribution.

• Fit inter-arrival times, demand rates, or other stochastic inputs to theoretical distributions.
• Replace limited historical data with statistically sound models for simulation.
• Improve model accuracy and robustness by selecting distributions based on statistical evidence rather than assumptions.
• 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.

ExtendSim Integration

Stat::Fit is integrated directly into the ExtendSim Random Number (Value library) block, allowing users launch the application directly from within ExtendSim, analyze data, and seamlessly import fitted parameters into simulation blocks.

Stat::Fit® is included with ExtendSim DE and Pro. For ExtendSim CP users, Stat::Fit® can be purchased separately and used alongside your models.

Commercial vs. Student License

Stat::Fit® is licensed for one user on one computer.

Commercial licenses can manage up to 50,000 data points.

The Student Version of Stat::Fit® is limited to 50 points as input data and seven common distributions (Binomial, Exponential, Lognormal, Normal, Pareto, Poisson, Uniform), but otherwise has the same functionality as the commercial version. The student version will not run along with the commercial version or any of the versions bundled with simulation software; please uninstall the student version before loading any other version.
