loglik.eccc {ccgarch}R Documentation

The log-likelihood function of the (E)CCC-GARCH model

Description

This function computes a log-likelihood of a (E)CCC-GARCH(1,1) model.

Usage

   loglik.eccc(param, dvar, model)

Arguments

param a vector of all the parameters in the (E)CCC-GARCH model
dvar a matrix of the observed residuals (T times N)
model a character string describing the model. "diagonal" for the diagonal model and "extended" for the extended (full ARCH and GARCH parameter matrices) model

Value

the negative of the (E)CCC-GARCH log-likelihood
