摘要 根据g-h分布的统计特性,提出了基于投资组合极端损失的V aR计算方法——g-h V aR法.该方法结合了分析方法、历史模拟方法和极值理论方法的优点,能够较好地处理组合回报的不对称现象的厚尾现象.证券市场的实证研究表明,该方法优于常用的δ-正态方法. According to the statistical properties of g-h distribution, a g-h VaR method was presented based on the extreme loss of the portfolio. This method compounds the merits of history simulation method, analytical method and the extreme theory method. The research on stock market shows that this g-h VaR method gains an advantage over δ-normal model.
