WebEstimate the univariate GARCH models for conditional volatility. Estimate the DCC model for conditional correlations. In the second step of estimating the DCC model, we use a new matrix Qt, representing a proxy correlation process. The first equation describes the relationship between the conditional correlation matrix Rt and the proxy process Qt. http://ebooks.ien.bg.ac.rs/205/1/jm_2008_01.pdf
