In hoanguc3m/ccgarch: Conditional Correlation GARCH models

Description

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

Usage

    dcc.estimation2(dvar, para, gradient=0)

Arguments

dvar	a matrix of the standardised residuals (T \times N)
para	a vector of the DCC parameters (2 \times 1)
gradient	a switch variable whether to use the gradient in the constraint optimisation. passed to constrOptim

Value

a list of the estimation results. See the explanations for constrOptim.

Note

dcc.estimation2 is a wrapper to constrOptim. The restrictions are α + β ≤q 1 and α, β ≥q 0 in the DCC equation.
