Besides a comparison of the characteristic line, the normalized mean square root error, the normalized mean error, and the maximum deviation are calculated and discussed.

除了用单行数值比较法外，还计算了重组和数学模型之间的归一化均方根偏差、归一化平均偏差和最大偏差。

What we want to do now is compute the mean and variance of the portfolio-- or the mean and standard deviation, since standard deviation is the square root of the variance-- for different combinations of the portfolios.

我们现在要做的是,计算这个投资组合的均值和方差-,或者均值和标准差，因为标准差的平方就等于方差-,这对任何投资组合都是一样的。
