Overview

ExpertFit will automatically and accurately determine which probability distribution best represents your data set, and typically will do so in less than a second. ExpertFit has 40 distributions, 30 high-quality graphical plots, 4 technically correct goodness-of-fit tests, sample sizes of 100,000, interactive histograms, extensive support for simulation modeling, a distribution viewer, batch mode, comprehensive context-sensitive help, and a User’s Guide with 8 complete examples.

Don’t be mislead by other distribution-fitting packages that have a small fraction of ExpertFit’s features, inferior distribution-selection algorithms, statistically invalid goodness-of-fit tests, and limited graphics and documentation.

Discrete-Event Simulation

Distribution-Function-Differences Plot

These versions of ExpertFit are designed for people who are doing discrete-event simulation. They will put the selected distribution into the proper format for direct import into 19 simulation-software packages. They also provide extensive support for choosing a distribution in the absence of data, including models for task times and for random equipment breakdowns.
