回帖推荐caibloodhoof 发表于3楼 查看完整内容 The first column is obtained as follows: At First, we generate n samples of size 1, 2, 5,10, 20 ...500, respectively. Then calculate the mean of each sample. At last, the standard deviation of n means is calculated, which is what you see in the first column. Please note that n is used since that we can't tell the number of sample from the information you provided.
