Laplace Distribution Functions

Description

Functions to compute the probability density function, cumulative distribution function, and quantile function for the Laplace distribution.

Usage

laplace_distribution(location = 0, scale = 1)

laplace_pdf(x, location = 0, scale = 1)

laplace_lpdf(x, location = 0, scale = 1)

laplace_cdf(x, location = 0, scale = 1)

laplace_lcdf(x, location = 0, scale = 1)

laplace_quantile(p, location = 0, scale = 1)

Arguments

location	location parameter (default is 0)
scale	scale parameter (default is 1)
x	quantile
p	probability (0 <= p <= 1)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.
