In the aspect of multivariate modeling, three forms of multivariate GARCHSK model includes vector form, diagonal form and simplify form, are put forward and compared. The famous dimension disaster exists in multivariate GARCHSK model also. Based on Independent Component Analysis, multivariate volatilities of conditional higher moments are estimated through IC-GARCHSK model, which make dynamic relation of higher moment risk between multi-assets to be possible.

鉴于多元 GARCHSK 模型存在严重的"维数灾难"问题，基于独立成分分解技术提出 IC-GARCHSK 模型，给出多元条件高阶矩波动率的估计方法，使得同时度量多个资产高阶矩风险之间动态关系成为可能，为利用组合投资方式分散高阶矩风险的影响奠定了方法论基础。

Based on my research, the transition matrix, if it exists, has to be diagonal matrix (Bai, 1998), or a m -vector.

根据我的研究，"转移矩阵"如果存在，它一定取"对角矩阵"的形式(Bai， 1998)，或"多元向量"的形式。

In this paper we obtain some new determination conditions from three aspects according to some exists theory and the property of αdiagonally dominant matrix, improve the determination conditions and give some numerical example to show our theory is effective.

本文根据α-对角占优矩阵的性质，从三个方面获得了一些新的判定条件，改进了某些已有判定条件的范围，并用数值例子进行了比较。
