2 . the stable asymmetric power - garch model is applied to szsi and shci and stable law is fitted into the empirical distributions . the stability of standardized stable innovation is checked and the evaluation of prediction accuracy is performed 2 .对szsi以及shci建立了非对称稳定幂- garch模型，对其标准稳定新息进行了稳定分布拟合、稳定性检验以及预测精确性的实证检验。
