public class DistributionFactory

extends Object

A class to easily generate statistical distributions for the AgentDistribution class. These distributions are from the colt library. All of the distributions require a set of doubles. For information on these distributions and the parameter lists, see the colt documentation.

Some examples include:

chi-squared : double degrees of freedom pareto: double scale, double shape poisson: double mean uniform: double min, double max

Note: The binomial distribution cannot be created from this Factory.
