NO.PZ2019040801000068 问题如下 Analysts' concern for Monte Carlo simulations is the size of the sampling error. Antithetic variate technique is effective wto rethe sampling error. In the following statements, whiscribes the antithetic variate technique most accurately? A.The simulation is rerun using a complement set of the originset of ranm variables. B.The process of ta generating is approximaterefining the unknown variable with a variable thhknown properties. C.In orr to resampling error, analysts enlarges the number of replications. In orr to make sure ththe probability of sample ta being reawn is equal, analysts shoulreplathe sample ta after every replication. A is correct.考点Antithetic Variates解析本题考查的是关于Antithetic Variates的结论。这句结论“The antithetic variate technique reces Monte Carlo sampling error rerunning the simulation using a complement set of the originset of ranm variables.”在基础班讲义上有。 老师好，看其他解答还是不太明白这个rerun的过程是什么样的？在antithetic variates的方法中，是否代表一次随机过程要得出两组随机数？（所谓的对偶过程）？这样的话不就相当于时间和模拟次数都翻倍了吗？还是说生产一正一反的两组数据算作一次模拟？这个具体的过程能否一下，谢谢！
