“利用MAE寻求最小误差的平滑系数α”之质疑

Querying the Validity of “Use MAE to Calculate the Level and Smooth a Coefficient of Least Error”

一次指数平滑法作为一种预测方法 ,对于平滑系数的选取通常是利用绝对差 (均方差 )进行误差估计 ,令人颇为困惑。本文旨在进一步探究平滑系数选取的理论依据 。

Level and smooth method of the first degree index is a forecasting method.As far as selection of level and smooth coefficient is concerned,the method is to make use of absolute error(mean square deviation) to calculate the error,which is puzzling.This paper is to study the theoretical basis of the selection of level and smooth coefficient in order to avoid its misunderstanding in practical application.
