what if问题是什么

问题如下：

A limitation of Monte Carlo simulation is:

选项：

A.

its failure to do "what if" analysis.

B.

that it requires historical records of returns

C.

its inability to independently specify cause-and-effect relationships.

解释：

C is correct.

Monte Carlo simulation is a complement to analytical methods. Monte Carlo simulation provides statistical estimates and not exact results. Analytical methods, when available, provide more insight into cause-and-effect relationships

蒙特卡洛模型是没有办法单独分辨因果关系的。这是analytical method才能做到的。所以说蒙特卡洛是analytical method的一个补充。
