求翻译：经过以上计算以及图表情况反应，利用加权移动平均法预测短时交通流量的精确度优于简单移动平均法，而且在移动平均项数N=3的情况下，加权系数取w1=0.5 ，w2 =0.3， w3 =0.2，的计算精度优于加权系数为 w1=0.4 ，w2 = w3 =0.3 的精度。是什么意思？

After the reaction of the above calculations and charts, using a weighted moving average method to forecast short-term traffic flow accuracy is better than the simple moving average, moving average number of n = 3 case, the weighting factor to take w1 = 0.5, w2 = 0.3, w3 = 0.2, calculation accuracy

As a result of these calculations, as well as chart, use the weighted moving average traffic flow when predicting a short of accuracy better than simple moving average, and average number of entries in the Mobile N = 3, the weighting factor W1 = 0.5 , W2 =0.3 , W3 =0.2 , calculate the accuracy of be

Responded after above computation as well as the graph situation that, using the weighting moving average method forecast the short-time traffic flow the precision surpasses the simple moving average method, moreover counts N=3 in the motion average item in the situation, the weighting factor takes

After the above calculation and chart responses, weighted moving average method of accuracy of forecasting short-time traffic flow better than the simple moving average, and in the case of moving average number of items N=3, weighting factor W1=0.5,W2=0.3,w3=0.2, precision of calculation accuracy of

calculate the average absolute error 100 is more than 100:;
