同学,上午好。这句话contrast Monte Carlo and historical simulation approaches是指,我们要比较这两个方法,蒙特卡洛和历史模拟法。历史模拟法与蒙特卡洛模拟都是回测中最常见的两种方法。

同学,上午好。这两种模拟方法和historical scenario analysis在不同章节,联系不大。
historical scenario analysis examines the efficacy of a strategy in discrete historical environments, such as during recessions or periods of high inflation.考察了在离散的历史环境中(挑选某段历史时期),如衰退或高通胀时期,策略的有效性。
simulation, explores how a strategy would perform in a hypothetical environment specified by the user, rather than a historical setting,模拟使用的是假设环境。
