nntsSymmetricDensity {CircNNTSR}

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

Angle in radians

Value

The function returns the density function evaluated at theta

Note

The default values provide the uniform circular density
