Directional (version 4.0)

Probability density function of the von Mises-Fisher distribution: Probability density function of the von Mises-Fisher distribution

Description

Probability density function of the von Mises-Fisher distribution.

Usage

pvm(theta, m, k, rads = FALSE)

Arguments

theta

A numerical value, either in radians or in degrees.

m

The mean direction in radians or in degrees.

k

The concentration parameter, \(\kappa\).

rads

If the data are in radians, this should be TRUE and FALSE otherwise.

Value

The probability that of x being less than theta, where x follows the von Mises-Fisher distribution.

Details

This value calculates the probability of x being less than theta and is used by group.gof.
