rlaplace: Laplace (Double Exponential) Random Generation

In jmuOutlier: Permutation Tests for Nonparametric Statistics

Description

Laplace (double exponential) random generation with mean equal to mean and standard deviation equal to sd.

Usage

rlaplace(n, mean = 0, sd = 1)

Arguments

n	Number of observations. If length(n)>1, the length is taken to be the number required.
mean	Population mean.
sd	Population standard deviation.

Details

The Laplace distribution has density e^{-|x-μ| √{2} / σ} / (σ √{2}), where μ is the mean of the distribution and σ is the standard deviation.

Value

rlaplace generates random deviates.

Note

The formulas computed within rlaplace are based on the textbook by Higgins (2004).
