摘要
在期权定价的蒙特卡罗模拟中,重要性抽样是一种有效的方差减小技术。从理论上分析了重要性抽样技术在几种期权定价中的具体应用,通过实例说明了这种测度转化的运用以及最优漂移率水平的确定;给出了模拟的具体算法;用对比分析的方法实证模拟和检验了用最优漂移率水平进行重要性抽样能最大限度地减小估计方差。
Importance sampling technique is an effective variance reduction technique in Monte Carlo simulation method for pricing options.It attempts to reduce variance by changing the probability measure from which paths are generated.This paper analyzes theoretically the application of importance sampling technique in pricing several kinds of options,and illustrates the method through examples.Meantime,it gives the algorithms which drive the Monte Carlo simulation to estimate the price of option.At last,some practi...
