通过4种GARCH模型与3种残差分布假定组合对上证综指实证建模,发现残差分布假定对模型的预测能力有影响,学生t分布能较好的拟合上证综指收益率序列.
The daily stock return of Shanghai Securities Market is conducted by GARCH models with residual distributions. The residual distributions are influential to the model forecast ability, the student distribution t can be in the good fitting to the series.
