getBandWidth {overlap}

Optimal bandwidth calculation

Description

Calculates the optimal bandwidth for von Mises kernel density estimation for a given sample. Used internally by other functions in the package.

Usage

getBandWidth(A, kmax = 3)

Arguments

A

a vector of times of observations in radians, ie. scaled to [0, 2\pi].

kmax

maximum moment to use for estimation; see Ridout & Linkie 2009.

Value

Optimal bandwidth for the sample data, or NA if estimation fails.
