摘要我们给出了重要性抽样在Heston和Bates模型以及Heston-Hull-White和Heston-Cox-Ingersoll-Ross模型下的多资产期权中的应用。此外,我们还在多水平蒙特卡罗模拟中提供了一种有效的重要性抽样方案。在所有情况下,我们解释了如何使用似然比方法在不同的模拟方案中计算希腊人,以及如何将其与重要性抽样相结合来显著降低希腊人的方差。
Abstract We present an application of importance sampling to multi-asset options under the Heston and the Bates models as well as to the Heston-Hull-White and the Heston-Cox-Ingersoll-Ross models. Moreover, we provide an efficient importance sampling scheme in a Multi-Level Monte Carlo simulation. In all cases, we explain how the Greeks can be computed in the different simulation schemes using the Likelihood Ratio Method, and how combining it with importance sampling leads to a significant variance reduction for the Greeks.
