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.
