In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.
实证分析部分首先对样本基金进行统计描述,得出其收益序列均存在尖峰厚尾特征,不服从正态分布,因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征;并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征,因此可以选择GARCH类模型来描述这种特性,经过模型筛选,得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1,1)模型。

Results indicated that both the amount of bacteria, epiphyte and actionmyces sharply and the amounts of acarina, collembolan and nematode were increased by application of organic fertilizer and the combined application of inorganic fertilizer with organic fertilizer for a longtime. Soil animal collembolan and nematode were significantly related to soil organic material and available phosphorous and available nitrogen. Acarina was significantly related to soil organic phosphorous, available potassium and available nitrogen.
