Monte Carlo simulation methods are often used when analytic methods become intractable, and they typically give a modeler added insight into the structure of a problem. As reliability and lifetime models become less mathematically tractable, Monte Carlo methods will have increasing importance. The ...
Setting up a Monte Carlo Simulation in R A good Monte Carlo simulation starts with a solid understanding of how the underlying process works. For the purposes of this example, we are going to estimate the production rate of a packaging line. We are going to buy a set of machines that mak...

Monte Carlo Simulation,即蒙特卡洛模拟,是一种强大的工具,用于解决复杂问题,特别是那些难以通过传统解析方法求解的问题。它以概率分布为基础,通过随机抽样和统计方法来近似求解问题的结果分布。下面将详细介绍蒙特卡洛模拟的各个方面。 一、定义与原理 蒙特卡洛模拟是一种利用随机数生成器...
system.time()tells us that the code to run 5 different Monte Carlo simulations of 10,000 Bernoulli trials with sample size of 5 takes about 38 seconds to run on a MacBook Pro 15 with a 2.5 Ghz Intel i-7 processor. Therefore, we expect that the next simulation will take multiple minute...

重复r次 上述过程,得到r个独立同分布的样本Y^{(i)} = g({\bf X}^{(i)}),\ i = 1,...,r。 使用Y^{(i)}的平均值(样本均值)来近似E[g({\bf X})](总体均值)。 2. 两种常用的 MC 方法 MC 方法的原理是从总体中生成大量的样本,Stata 有两种常用的方法。第一种是使用postfile命令,另一种...
「JMP 3分钟玩转数据分析系列」视频之——蒙特卡罗模拟(Monte Carlo Simulation)。蒙特卡罗方法,又称随机抽样或统计试验方法,是以概率和统计理论方法为基础的一种计算方法。它将所求解的问题同一定的概率模型相联系,用计算机实现统计模拟或抽样,以获得问题的近似解。3
The Monte Carlo simulation is used to model the probability of different outcomes in a process that cannot easily be predicted because of the potential for random variables.
