loglik.dcc1 {ccgarch} | R Documentation |
This function returns a log-likelihood of the (E)DCC-GARCH in the first stage estimation.
loglik.dcc1(param, dvar, model)
param |
a vector of the parameters (npar times 1) |
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 |
the negative of the first stage log-likelihood
The function is used in optim
