NNTS Symmetric log-likelihood function

Description

Computes the log-likelihood function with NNTS symmetric density for data

Usage

nntsloglikSymmetric(cpars = c(0, 0), M = 0, data)

Arguments

cpars vector of real numbers of dimension M+1. 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
data vector with angles in radians. If data is a matrix the first column is used

Value

The function gives the value of the log-likelihood function for data

Note

The default values give the Uniform circular log-likelihood for data
