Then for each industry index return series, the GARCH model has been made. 对每个行业指数收益率(IR)序列建模之后,又进行了二元GARCH建模。
In the empirical study we also found the phenomenon of " fat tail " distribution, conditional variance and asymmetric variance of SH180 index return. 此外,在实证分析中,我们也发现并证实了上证180指数收益率(IR)存在“厚尾”分布、方差的时变性以及非对称性的风险特征。
Based on impulse response analysis and variance decomposition method, the transmission of innovations in the index return system and the response of variable effect are precisely described in the paper. 更进一步地利用脉冲响应分析及方差分解方法测算了新息在收益系统之间的传递、变量的响应效果和新息冲击在变量响应中的贡献程度。
The research in the probability distribution of stock market index return is of great importance to the exploration of the market efficiency, the pricing of financial assets as well as risk management. 股票指数收益率(IR)的概率分布的研究,对于探索股票市场的有效性、资产定价以及风险管理等问题都具有重要的现实意义。
