新的混合模型通过预测区间不确定性增强波动率预测能力

研究人员开发了一种结合GARCH和LSTM的新混合模型用于波动率预测,解决了评估预测不确定性的难题。该模型通过纳入ARMA结构来处理条件均值,并引入了前向bootstrap算法来生成多步预测区间,从而扩展了现有的GARCH-LSTM方法。为了提高区间覆盖率,该方法从经验分布中抽取bootstrap创新项以模仿金融序列的肥尾特性,并利用一致性预测原理系统地扩展区间长度。在模拟和2020-2025年美国股指上的评估表明,基于ARMA的混合模型实现了更低的点预测误差,而将这两种方法与基于均值的混合模型结合,可以得到最接近名义水平的区间。 AI

影响 为金融预测模型中的不确定性量化引入了新颖的方法,有望改善风险管理。

    混合模型在已实现波动率预测中的预测推理

    arXiv:2611.13212v1 Announce Type: cross Abstract: GARCH-LSTM hybrid models have become increasingly popular in the volatility forecasting literature. To date, these models have almost exclusively focused on point estimation and accuracy measures such as RMSE and MAPE, while faili…
