摘要
为提高预测模型的预测精度 ,从几个角度研究了预测模型中参数估计的优化方法 ,并利用欧氏空间的距离将建立趋势预测模型的折扣最小一乘法推广到建立一般因果关系的回归预测模型 .
In order to improve the precision of forecasting model, this paper studies optimal method for estimating parameters in predicting model from several sides ,and develops the method of discount least absolute value that is used as constructing general regressive forecasting model by the use of Euclidean distance.
