conditional covariance with mgarch dcc
Posted: Fri Apr 24, 2015 2:04 am
Hello,
I need to find conditional covariances between two variables. My method is mgarch dcc. When I run mgarch dcc codes, it produces garch(1), garch(2) and rho. I calculate covariance as
covariance=rho*(garch(1)*(garch(2))
as the codes don't produce covariances, it must be the way to estimate covariances .
However, I also estimated the covariances with mgarch ccc which produces the covariances. And mgarch ccc produces better results than dcc in my research so I felt dubious whether covariance=rho*(garch(1)*(garch(2)) might be wrong or I have missed something.
Thank you very much,
