est.kappa {tectonicr}

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

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