Laplace {rmutil}

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) = \frac{\exp(-abs(y-\mu)/\sigma)}{(2\sigma)}

where \mu is the location parameter of the distribution and \sigma 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.
