WebTo this end two models are used. The first model is the constant correlation multivariate GARCH model developed by Bollerslev (1990). The model has the advantage of reducing the number of parameters to be estimated to 3p + p(p−1)/2 where p is the number of financial returns. Variances are estimated using a simple GARCH(1,1) formulation:
