Using the standard deviation coefficient as analysis target, the author provides a new probability analysis method, in case the mathematical expectations are different.

提供了一个在数学期望值不相等条件下进行概率分析的新方法，该方法采用所谓标准差系数作为分析指标。

The precision of an analytical procedure is usually expressed as the standard deviation or relative standard deviation (coefficient of variation) of a series of measurements.

分析规程的精密度通常以一系列测量数值的标准差或相对标准差(变异系数)来表示。

It is found that the more the variance explained by the linear model, the smaller the standard deviation of regression coefficient.

拟合方差与回归系数标准偏差存在明显的相关关系。线性模型能解释的方差越大，回归系数标准偏差越小。

Once you know the average return, the standard deviation of each index and the correlation coefficient between each pair of indexes, the rest is math.
