摘要
在对某经济变量预测中,采用了霍尔特 温特斯指数平滑法和利用季节指数修正二次指数平滑值方法,从中选择一个误差小、精度高、令人满意的预测法。
In the prediction of a certain economic variable, two methods have been applied:the C.C.HoltP.R.Winters exponential smoothing method, and the method of correcting the second order exponential smoothing value by season index number. Then the one with smaller error and higher precision is selected.
