nntsloglikInterval0to2pi: NNTS log-likelihood function for the incidence data defined in the interval [0,2*pi)

Description

Computes the log-likelihood function for incidence data (number of observed values in certain intervals defined in the interval [0,2*pi))

Usage

nntsloglikInterval0to2pi(data, cutpoints, cpars = 1/sqrt(2 * pi), M = 0)

Value

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

Arguments

data

Number of observations in each interval

cutpoints

Vector of size length(data)+1 with the limits of the exhaustive and mutually exclusive intervals in which the interval [0,2*pi) is divided.

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 density
