Parameters:

name - Name of the standard Laplace Distribution (will be prefixed with StandardLaplaceDistribution_)

Method Detail

draw

public double draw()

Description copied from class: UnivariateDistribution

Draw a value from the distribution according to the distribution at hand

Specified by:

draw in class UnivariateDistribution

Returns:

A double number drawn from the modeled distribution
