Generalized autoregressive conditional density model provides a useful tool for simulating the probability density function of financial asset returns.It is important to describe the dynamic character of financial asset return comprehensively.Based on univariate GARCD-JSU model,the multivariate GARCD-JSU model has been proposed in the paper.First,we give the vector expression of the new model.Second,the reducing expression is obtained by dynamic conditional correlation method.Third three-stage m...
