dlaplace {jmuOutlier}

Laplace (Double Exponential) Density Function

Description

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

Usage

dlaplace(x, mean = 0, sd = 1)

Arguments

x

Vector of quantiles.

mean

Population mean.

sd

Population standard deviation.

Details

The Laplace distribution has density e^{-|x-\mu| \sqrt{2} / \sigma} / (\sigma \sqrt{2}), where \mu is the mean of the distribution and \sigma is the standard deviation.

Value

dlaplace gives the density.

Note

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