public class ColtChiSquare extends ColtRandomSource
This actor instantiates a cern.jet.random.ChiSquare object with freedom argument set to 1.0. The Chi Square Distribution is
A special case of the Gamma distribution.The above description of Chi Square is copyrighted.p(x) = (1/g(f/2)) * (x/2)^(f/2-1) * exp(-x/2) with g(a) being the gamma function and f being the degrees of freedom.
Valid parameter ranges: freedom > 0.
A definition of the ChiSquare distribution can be found at
