Levy {rmutil} | R Documentation |
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.dlevy(y, m, s) plevy(q, m, s)
y |
vector of responses. |
q |
vector of quantiles. |
m |
vector of location parameters. |
s |
vector of dispersion parameters. |

dnorm
for the normal distribution and
dcauchy
for the Cauchy distribution, two other stable
distributions.
