vonmises: The von Mises Distribution

In tectonicr: Analyzing the Orientation of Maximum Horizontal Stress

The von Mises Distribution

Description

Density, probability distribution function, quantiles, and random generation for the circular normal distribution with mean and kappa.

Usage

rvm(n, mean, kappa)

dvm(theta, mean, kappa)

pvm(theta, mean, kappa, from = NULL, tol = 1e-20)

qvm(p, mean = 0, kappa, from = NULL, tol = .Machine$double.eps^(0.6))

Arguments

n	number of observations in degrees
mean	mean in degrees
kappa	concentration parameter
theta	angular value in degrees
from	if NULL is set to \mu-\pi. This is the value from which the pvm and qvm are evaluated. in degrees.
tol	the precision in evaluating the distribution function or the quantile.
p	numeric vector of probabilities with values in [0,1].

Value

dvm gives the density, pvm gives the probability of the von Mises distribution function, rvm generates random deviates (in degrees), and qvm provides quantiles (in degrees).

Examples

x <- rvm(100, mean = 90, kappa = 2)
dvm(x, mean = 90, kappa = 2)
pvm(x, mean = 90, kappa = 2)
qvm(c(.25, .5, .75), mean = 90, kappa = 2)
