axialnntsdensity: NNTS density function for axial data

Description

Density function for the NNTS axial model

Usage

axialnntsdensity(data, cpars = 1/sqrt(pi), M = 0)

Value

res

The function returns a 1 by R matrix with the density function evaluated at each element of the vector data of size R

Arguments

data

Vector of size R with axial angles in radians

cpars

Vector of complex numbers of dimension M+1. The first element is a real and positive number. The sum of the squared moduli of the c parameters must be equal to 1/pi

M

Number of components in the NNTS axial model
