Class Logarithmic

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


    public class Logarithmicextends AbstractContinousDistribution
    Logarithmic distribution.

    Valid parameter ranges: 0 < p < 1.

    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.

    Implementation:

    Method: Inversion/Transformation.
    This is a port of lsk.c from the C-RAND / WIN-RAND library. C-RAND's implementation, in turn, is based upon

    A.W. Kemp (1981): Efficient generation of logarithmically distributed pseudo-random variables, Appl. Statist. 30, 249-253.
