Data Simulator Available in NCSS

NCSS
Data Simulator

This procedure allows you to simulate, store, and visualize data from various discrete and continuous distributions, including Beta, Binomial, Cauchy, Constant, Exponential, F, Gamma, Multinomial, Normal, Poisson, T, Tukey's Lambda, Uniform, and Weibull. Mixture distributions may also be simulated. This module creates a histogram of a specified distribution as well as a numerical summary of simulated data. By storing the data, you can investigate the effects of varying data distributions on hypothesis tests and confidence intervals for your specific investigational situation.
