We propose to generalize the Wishart state-space model for realized covariance matrices of asset returns in order to capture complex measurement error structures induced by heterogeneous liquidity across assets. Our model assumes that the latent covariance matrix of the assets is observed...

We propose a dynamic factor state-space model for the prediction of high-dimensional realized covariance matrices of asset returns. Using a block LDL decomposition of the joint covariance matrix of assets and factors, we express the realized covariance matrix of the individual assets similar to...

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 …
