Class DiscreteLaplace

java.lang.Object

jdistlib.generic.GenericDistribution

jdistlib.DiscreteLaplace

All Implemented Interfaces:

SupportedDistribution

public final class DiscreteLaplace
extends GenericDistribution
implements SupportedDistribution

Discrete Laplace distribution on the lattice location + Z.

The probability of location + k is (1 - p) / (1 + p) * p^abs(k) for integer k and 0 < p < 1.
