ZRandom implements high quality random number generation for Microsoft Excel using the Merssenne Twister algorithm :
* Use higher quality pseudo-random numbers than the Excel RAND() and VBA Rnd() functions. * Generate random numbers from 16 discrete and continuous distributions. ZRandom implements the following discrete distributions: Uniform, Bernoulli, Geometric, Hypergeometric, Negative Binomial and Poisson. ZRandom implements the following continuous distributions: Beta, Burr, Exponential, Gamma, Lognormal, Normal, Pareto, Triangular, Uniform and Weibull. * Create large batches of random numbers using the interactive user interface. * Excel functions for use in spreadsheet formulas. * Random Sort and Random Sample * Interactive distribution wizard * A VBA interface to generate random numbers in your code.
