nntsloglikSymmetric {CircNNTSR}

NNTS symmetric log-likelihood function

Description

Computes the log-likelihood function with NNTS symmetric density for the 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. The first column is used if data are a matrix

Value

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

Note

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