So two methods are used to remove the local relation. One is that extremal index is introduced to POT model. The analysis showed that the introduction of extremal index improves validity and veracity of VaR based on POT model. Still VaR based on POT model introducing extremal index is invalid in low confidence level. The other is to filter returns series using GARCH model.

为此引入两种方法来消除超阈值的局部相关性：一是将极值指标引入到POT模型中，实证分析发现极值指标的引入不仅改善了POT模型估计VaR的有效性，而且还提高了POT模型估计的准确性，尽管如此在较低的置信水平上即便引入极值指标，POT模型估计VaR仍是无效的；二是用GARCH模型对收益率序列进行过滤处理。
