wrpcauchy: wrapped Cauchy distribution

Description

Density and random generation for the wrapped Cauchy distribution.

Usage

dwrpcauchy(x, mu = 0, rho, log = FALSE)
rwrpcauchy(n, mu = 0, rho, wrap = TRUE)

Value

dwrpcauchy gives the density and rwrpcauchy generates random deviates.

Arguments

x

vector of angles measured in radians at which to evaluate the density function.

mu

mean direction of the distribution measured in radians.

rho

concentration parameter of the distribution, must be in the interval from 0 to 1.

log

logical; if TRUE, densities are returned on the log scale.

n

number of random values to return.

wrap

logical; if TRUE, generated angles are wrapped to the interval from -pi to pi.

Details

This implementation of dwrpcauchy allows for automatic differentiation with RTMB. rwrpcauchy is simply a wrapper for rwrappedcauchyimported from circular.

Examples

set.seed(1)
x <- rwrpcauchy(10, 0, 0.5)
d <- dwrpcauchy(x, 0, 0.5)
