Dynamic Conditional Correlation (DCC) model by allowing for a clustering structure of the univariate GARCH parameters. The … model can be estimated in two steps, the first devoted to the clustering structure, and the second focusing on correlation …

We address some issues that arise with the Dynamic Conditional Correlation (DCC) model. We prove that the DCC large … system estimator (DCC estimator) can be inconsistent, and that the traditional interpretation of the DCC correlation … parameters can lead to misleading conclusions. We then suggest a more tractable dynamic conditional correlation model (cDCC model …

We construct a parsimonious test of constancy of the correlation matrix in the multivariate conditional correlation … deterministically as a function of time. The alternative is a covariance matrix, not a correlation matrix, so the test may be viewed as … a general test of stability of a constant correlation matrix. The size of the test in finite samples is studied by …
