The GARCH-DCC Model and 2-stage DCC(MVT) estimation.

This short demonstration illustrates the use of the DCC model and its methods using the rmgarch package, and in particular an alternative method for 2-stage DCC estimation in the presence of the MVT distribution shape (nuisance) parameter. The theoretical background and representation of the model is detailed in the package’s vignette. The dataset and period
