nntsSymmetricDensity: 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
