The Mean Absolute Percentage Error（MAPE） for one-step ahead prediction is 1.382%，and MAPE for the 6 steps are all less than 6%.The prediction result is of high precision. 所应用方法的一步预测值平均绝对百分比误差MAPE为1.
Because some actual prices are zero or close to zero, traditional error index - mean absolute percentage error (MAPE) becomes unreasonable and a modified MAPE is adopted. 实验也表明，当电价中不存在零或者接近于零的电价时，传统的MAPE指标与修正后的MAPE指标之间相差甚少。
The mean absolute percentage error (MAPE) and the root of mean square error (RMSE) of WA-SVM method was 0.04937 and 0.3453 respectively, whereas MAPE and RMSE of SVM method were 0.08493 and 0.6319. WA-SVM方法预测精度较SVM方法有较大提高，其平均绝对百分比误差和均方根误差分别为0.
That hill's an absolute doddle (to climb). (爬)上那座山岗毫不费力。
What percentage of the earth is covered by oceans? 地球上百分之多少被海水覆盖着？
We now have the absolute proof of his guilt. 我们现在有他犯罪的确凿证据。
