NNTS density function
Description
Density function for the NNTS model
Usage
nntsdensity(data, cpars = 1/sqrt(2 * pi), M = 0)Arguments
data |
Vector of 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/(2*pi). |
M |
Number of components in the NNTS |
Value
The function returns the density function evaluated at each point in data
