摘要
讨论了一个非对称广义自回归条件异方差新模型的严平稳性及遍历性,并且给出了该模型存在高阶矩的条件.
In this paper, the author discuss the strict stationary property and the ergodicity of a new model for asymmetric general autoregressive conditional heteroskedasticity, and give the sufficient conditions for the existence of evenorder moments of the model.
