Description Usage Arguments Value References See Also

Description

Computes the maximum likelihood estimates for the parameters of a von Mises distribution: the mean direction and the concentration parameter.

Usage

1
vm.ml(x, bias=FALSE)

Arguments

x

vector of angular measurements in radians.

bias

logical flag: if TRUE, the estimate for kappa is computed with a bias corrected method. See est.kappa. Default is FALSE, i.e. no bias correction.

Value

Returns a data frame with two components: mu and kappa, the MLES of the respective parameters.
