Consider n time series of returns and make the usual assumption that returns are serially uncorrelated. Then, we can define a vector of zero-mean white noises εt=rt-μ, where rt is the n⨯1 vector of returns and μis the vector of expected returns. Despite of being serially uncorrelated, the returns may present … See more The estimation of one GARCH model for each of the n time series of returns in the first step is standard. For details on GARCH estimation, see GARCH documentation. For … See more The specific model just described can be generalized in two ways.
