est.kappa: Concentration parameter of von Mises distribution

In tectonicr: Analyzing the Orientation of Maximum Horizontal Stress

Concentration parameter of von Mises distribution

Description

Computes the maximum likelihood estimate of \kappa, the concentration parameter of a von Mises distribution, given a set of angular measurements.

Usage

est.kappa(x, w = NULL, bias = FALSE, ...)

Arguments

x	numeric. angles in degrees
w	numeric. weightings
bias	logical parameter determining whether a bias correction is used in the computation of the MLE. Default for bias is FALSE for no bias correction.
...	optional parameters passed to circular_mean()

Value

numeric.

Examples

set.seed(123)
est.kappa(rvm(100, 90, 10), w = 1 / runif(100, 0, 10))
