问题如下:
For two Monte Carlo simulations, one with 50 replications has a standard deviation of 18.6, the other with 800 relications has a standard deviation of 17.8, what are the standard error estimates for these two simulations?
选项:
解释:
C is correct.
考点:标准误
解析:monte carlo simulation中,标准误的计算就是用标准差除以重复次数的平方根,即:18.6/(50^0.5)= 2.63 和 17.8/(800^0.5)= 0.63
老师你好,这里已经有标准差了,为什么还需要计算标准误呢
