Circular Mode

Source: R/statistics.R
circular_mode.Rd

MLE angle (maximum density) using a von Mises distribution kernel with specified concentration.

Usage

circular_mode(x, kappa = NULL, axial = TRUE, n = 512)

Arguments

x

numeric vector. Values in degrees.

kappa

von Mises distribution concentration parameter. Will be estimated using est.kappa() if not provided.

axial

logical. Whether the data are axial, i.e. pi-periodical (TRUE, the default) or directional, i.e. \(2 \pi\)-periodical (FALSE).#' @param kappa

n

the number of equally spaced points at which the density is to be estimated.

Value

numeric
