Levy {rmutil}R Documentation

The Levy Distribution

Description

These functions provide information about the Levy distribution with location parameter equal to m and dispersion equal to s. dlevy gives the density, plevy gives the distribution function.

The Levy distribution has density

f(y) = sqrt(s/(2 pi (y-m)^3)) exp(-s/(2 (y-m)))

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

Usage

dlevy(y, m, s)
plevy(q, m, s)

Arguments

y vector of responses.
q vector of quantiles.
m vector of location parameters.
s vector of dispersion parameters.
