R: Laplace Distribution

Laplace {rmutil} | R Documentation

## Laplace Distribution

### Description

These functions provide information about the Laplace distribution with location parameter equal to `m` and dispersion equal to `s`: density, cumulative distribution, quantiles, log hazard, and random generation.

The Laplace distribution has density

f(y) = exp(-abs(y-m)/s)/(2*s)

where m is the location parameter of the distribution and s is the dispersion.

### Usage

    dlaplace(y, m=0, s=1, log=FALSE)
    plaplace(q, m=0, s=1)
    qlaplace(p, m=0, s=1)
    rlaplace(n=1, m=0, s=1)

### Arguments

`y` | vector of responses.
`q` | vector of quantiles.
`p` | vector of probabilities
`n` | number of values to generate
`m` | vector of location parameters.
`s` | vector of dispersion parameters.
`log` | if TRUE, log probabilities are supplied.
