In hoanguc3m/ccgarch: Conditional Correlation GARCH models

Description

This function carries out the first stage (volatility part) estimation of the (E)DCC-GARCH model.

Usage

    dcc.estimation1(dvar, a, A, B, model, method="BFGS")

Arguments

dvar	a matrix of the data used for estimating the (E)DCC-GARCH(1,1) model (T \times N)
a	a vector of constants in the vector GARCH equation (N \times 1)
A	an ARCH parameter matrix in the vector GARCH equation (N \times N)
B	a GARCH parameter matrix in the vector GARCH equation (N \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
method	a character string specifying the optimisation method in optim. There are three choices, namely, "Nelder-Mead", "BFGS" (default) and "CG".

Value

a list of the estimation results. See the explanations in optim.
