In order to implement maximum likelihood, we assume the stacked return series r t = r 1,t r 2,t ′ is multivariate normal with a conditional covariance H t as defined above. One exception is the Spline-GARCH model of Engle and Rangel (2008) that. The main difference between the two is that in the latter, the conditional correlation matrix is not constant over time—we have R t instead of R. The input data are the residual series that we got from AR(1) model. I have done the following steps as you can see from my codes also, fitting the DCC Garch model with the normal distribution.
