mean absolute deviation

基本解释

The mean absolute deviation of the calculation results by this method from the experiment data was 14.9%.
该算法的预测值与实验数据相比，其平均绝对偏差为14．9％。
In this paper, based on the approach of a trade off between mean and absolute deviation, we investigate the portfolio performances of 169 A stocks in Shanghai stock market.
本文基于均值—绝对偏差的折中方法探讨了上海股票市场1 69种股票的投资组合分析，得到了一些有益的启示和结论。
We propose a mean semi-absolute deviation portfolio selection model with the restricted short selling. The model is a linear programming problem and is solved by the pivoting algorithm.
本文提出了限制性卖空的均值-半绝对偏差投资组合模型，通过变量替换将该模型转变为一般线性规划问题，从而运用线性规划的旋转算法进行求解。
