pvm

Probability density function of the von Mises-Fisher distribution

Probability density function of the von Mises-Fisher distribution.

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

`theta`	A numerical value, either in radians or in degrees.
`m`	The mean direction in radians or in degrees.
`k`	The concentration parameter, κ.
`rads`	If the data are in radians, this should be TRUE and FALSE otherwise.

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

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