This thesis is to analyze the coefficient of standard deviation of the earnings before interest and tax and the earnings per share.

在销售量为随机变量的时候，本文利用标准差系数来讨论销售量、税息前收益和税后收益的波动程度之间的联系。

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.
