dcauchy(x, location = 0, scale = 1) pcauchy(q, location = 0, scale = 1) qcauchy(p, location = 0, scale = 1) rcauchy(n, location = 0, scale = 1)
location
and scale parameter scale
.
dcauchy
, pcauchy
, and qcauchy
are respectively
the density, distribution function and quantile function of the Cauchy
distribution. rcauchy
generates random deviates from the
Cauchy.
The Cauchy distribution with location l and scale s has density
f(x) = 1 / (pi s (1 + ((x-l)/s)^2))
for all x.dt
for the t distribution which generalizes
dcauchy(*, l = 0, s = 1)
.
dcauchy(-1:4) == 1 / (pi*(1 + (-1:4)^2))
