nntsloglik {CircNNTSR} | R Documentation |
Computes the log-likelihood function with NNTS density for data
nntsloglik(cpars = c(0, 0), M = 0, data)
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 M numbers are the arguments of the c parameters |
M |
number of components in the NNTS |
data |
vector with observed angles in radians. |
The function gives the value of the log-likelihood function for the data
The default values give the Uniform circular log-likelihood for data
