Class VonMises

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


    public class VonMisesextends AbstractContinousDistribution
    Von Mises distribution.

    Valid parameter ranges: k > 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.

    Implementation:

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

    D.J. Best, N.I. Fisher (1979): Efficient simulation of the von Mises distribution, Appl. Statist. 28, 152-157.
