dpowbat: The von-Mises based symmetric power Batschelet distribution

In keesmulder/flexcircmix: Fit Mixtures of Flexible Circular Distributions

Description

The power Batschelet distribution, with mean direction mu, concentration parameter kp, and shape (peakedness) parameter lam. This is the von Mises based version, without a skewness parameter.

Usage

dpowbat(x, mu = 0, kp = 1, lam = 0, log = FALSE)

Arguments

x	An angle in radians.
mu	A mean direction, in radians.
kp	Numeric, > 0,the concentration parameter.
lam	The shape parameter (peakedness), -Inf < lam < Inf
log	Logical; whether to return the log of the probability or not.

Value

Numeric; Either the probability or log-probability of angle x given the parameters.

Examples

dpowbat(3)

# Flat-topped distribution
curve(dpowbat(x, lam = -.8), -pi, pi)

# Peaked distribution
curve(dpowbat(x, lam = .8), -pi, pi)
