Wrapped Cauchy Density Function
Density, and random generation for the wrapped Cauchy circular distribution.
dwrappedcauchy(x, mu = circular(0), rho = exp(-1)) rwrappedcauchy(n, mu = circular(0), rho = exp(-1), control.circular=list())
x |
a vector. The object is coerced to class
|
n |
number of observations. |
mu |
mean direction of the distribution as a |
rho |
concentration parameter of the distribution. |
control.circular |
the attribute of the resulting object. |
dwrappedcauchy gives the density and rwrappedcauchy generates random deviates.
