应该是在除异方差用的方法那种吧，先求方差，把方差的倒数作为权数，在乘以各个值

谢谢楼上的前辈！

那么，乘以各个值的权数（方差的倒数）都是一个相同的值了？应该是这样吧？

我认为是的

谢谢楼上的学长！

When you calculate the estimate, say as the mean of some sample quantities, you should be able to get the variance estimate of the sample quantities also.
So for each of the estimate you give

estimate 0.85

1.05

1.57

3.36

3.88

3.63

3.50

3.97

Variance S1 S2 S3 ......

As a result, the weights for the eight estimate should be each calculated as W_j=(1/S_j)/Sum(1/S_k) , the sum is taken over all 8 estimates' variances.
