摘要
本文研究了AGARCH模型的一些性质.利用随机差分方程的有关结论,获得了AGARCH模型的尾行为和高阶矩存在的一个充分条件,结果表明这是对GARCH模型的相应的推广.
In the article, some properties of the asymmetric Garch model are studied. By using some results on stochastic difference equations, the tail behavior of the model and the sufficient condition for its higher moments existence are derived. The counterparts of the Garch model are extended.
