Class Logarithmic

All Implemented Interfaces:

public class Logarithmic
extends 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.
