loglik.dcc1: The 1st stage log-likelihood function for the (E)DCC GARCH
Description
This function returns a log-likelihood of the (E)DCC-GARCH model in the first stage estimation.
Usage
loglik.dcc1(param, dvar, model)
Arguments
param
initial values for a vector of the parameters $(npar \times 1)$
dvar
a matrix of the data $(T \times N)$
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 first stage log-likelihood
