Class Hyperbolic

  • All Implemented Interfaces:
    DoubleFunction, IntFunction, Serializable, Cloneable

    public class Hyperbolicextends AbstractContinousDistribution
    Hyperbolic distribution.

    Valid parameter ranges: alpha > 0 and beta > 0.

    Instance methods operate on a user supplied uniform random number generator; they are unsynchronized.

    Static methods operate on a default uniform random number generator; they are synchronized.


    Method: Non-Universal Rejection. High performance implementation.
    This is a port of hyplc.c from the C-RAND / WIN-RAND library. C-RAND's implementation, in turn, is based upon

    L. Devroye (1986): Non-Uniform Random Variate Generation, Springer Verlag, New York.
