摘 要: | 讨论了自回归条件异方差(Autoregressive Conditional Heteroskedastic,简称ARCH)模型在金融时间序列分析中的拟合应用,以一金融时间序列为例,通过SAS/ETS中的自回归(Autoreg)程实现对该金融时间序列的自回归一广义自回归条件异方差(Autoregressive—generalized ARCH,简称AR—GARCH)模型的拟合和分析,最终得到理想结果.

Abstract: | This paper discusses the fitting application of the autoregressive conditional heteroskedasticity (ARCH) model in the financial time series.Take a group of financial time series for example, then use the Autoreg process in the SAS/ETS to achieve the fitting of the autoregression - generalized autoregressive conditional heteroske- dasticity (AR- GARCH) model and finally get perfect result. |
