设计和测试模型的过程:
The process of design and the testing model:
计算出五年内的移动平均数.
To work out the average movement value within the past 5 years.
(1)调整五年内的移动平均数.
To adjust the average movement value within the past 5 years.
(2)对前三年得数据建模,计算前三年的季节指数.
To build a model using the previous / past 3 year's data,work out the seasonal index of the previous / past 3 year.
(3)根据前三年调整后的移动平均数来计算预期中位数.
Use the adjusted average movement value of the previous / past 3 years to work out the medium of the forecast period.
(4)根据预期的中位数来计算实际的中位数.
To work out the actual medium through using of the medium of the forecast period.
(5)计算剔除季节性因素后的数据.
Work out the data after taking away the seasonal factors.
(6)剔除季节性因素后计算最佳离合线.
Worl out the best clutch line after taking away the seasonal factor.
(7)预测第四年的移动平均值和计算预测销售量.
Forecast the 4th year's average movement value and the forecast sales.
(8)将预测销售量量和实际销售量做在一个XY散点图上进行比较.
Use the forecast sales values and the actual sales value to draw a scattered point diagram to carry out a comparison.
(9)计算绝对误差和绝对方差,进而计算MAE和MSE
Calculate the absolute error and the absolute variance and to work out the MAE and MSE.
(10)使用卡方检验对预测值进行检验.
To carry out the forecast value's testing by using of the Chi-square value test.
