public class ColtBeta extends ColtRandomSource
This actor instantiates a cern.jet.random.Beta object with alpha and beta both set to 2.0.

The above description of beta() is copyrighted.beta
public static double beta(double a, double b, double x)Returns the area from zero to x under the beta density function.
x - - | (a+b) | | a-1 b-1 P(x) = ---------- | t (1-t) dt - - | | | (a) | (b) - 0This function is identical to the incomplete beta integral function Gamma.incompleteBeta(a, b, x).
The complemented function is
1 - P(1-x) = Gamma.incompleteBeta( b, a, x );
