SIPmath Tools 3rd Generation


Free Version


Creates interactive simulations in Excel that run without macros or add-ins using the data table. Can perform thousands of trials per keystroke.

Seed-able real time random number generator using native Excel formulas from Hubbard Decision Research.

16 distributions, including Poisson and Tom Keelin’s Metalog.

Uses Cholesky factorization to generate correlated normal or uniform variables. The latter may be used with other variates, such as Poisson, etc.

Creates models with up to 1 million trials and hundreds of output cells (but not at once).

Multi-Experiment mode: runs multiple simulation experiments with a single output cell to experiment with key parameters of the model.

Save current simulation results to Excel SIP library.

Import and export SIP libraries to or from XML, CSV, or JSON for interchange with R, Matlab, or nearly any environment supporting arrays.

Import SIP libraries from @RISK and Crystal Ball Models.

Includes one hour of technical support.




New Enterprise SIPmath™ Modeler Tools announces a paid Windows Enterprise version of our our SIPmath Modeler Tools for Excel. We still recommend that you download the Standard SIPmath Modeler Tools for Windows or Mac at no charge to get your feet wet. Then move up to the paid version when you need more performance, more support, and less guilt.

More Performance: See the chart to the left for a comparison of the standard and enterprise versions.

More Support: Receive one hour of technical support, and free attendance to all of our remaining 2017 webinars when you purchase the Enterprise SIPmath Modeler Tools.

Less Guilt: Both versions of the SIPmath tools are unique in that they create blindingly fast simulation models that run without the tools themselves (see below). We know that many of our users feel guilty about using such a great product without supporting nonprofit The fee of $500 for the Enterprise version will make you proud to have helped us fulfill our mission of improving the communication of uncertainty through education, best practices, and standards.
