nntsSymmetricDensity {CircNNTSR}R Documentation

Symmetric NNTS density function

Description

Density function for the Symmetric NNTS

Usage

nntsSymmetricDensity(cpars = c(0, 0), M = 0, theta)

Arguments

cpars vector of real numbers of dimension 2*M. The first M numbers are the SQUARED moduli of the c parameters, the sum must be less than 1/(2*pi). The last number is the mean of symmetry
M number of components in the NNTS
theta an angle in radians

Value

The function gives the density function evaluated at theta

Note

The default values give the Uniform circular density
