摘要
在Comte等关于二阶(非)因果关系的基础上,探讨了FF-GARCH模型、(G)O-GARCH模型、Hadamard乘积GARCH模型的波动(非)因果关系条件,为更好理解所得结论,给出了二维情况下的表达。同时,对多维SV模型也进行了分析。
In this paper, we study the conditions of no existing causal relationship about FF-GARCH model, (G)O-GARCH models, Hadamard product GARCH model, and especially, for the sake of under- standing these conditions, also pay attention to those bivariate case based on Comte and Lieberman's work. In addition, we discuss the conditions of multivariate stochastic variance (SV) model. All conclusions aboveare helpful for understanding the machine of financial market volatility.
