est.kappa {tectonicr} | R Documentation |
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, axial = TRUE)
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 |
axial |
logical. Whether the data are axial, i.e. pi-periodical
( |
Value
numeric.
Examples
set.seed(123)
est.kappa(rvm(100, 90, 10), w = 1 / runif(100, 0, 10))
