加权回归模型在公路主枢纽运输量预测中的应用

The Application of Weight Regression Model to Highway Main Hub Transportation Volume Prediction

根据预测时原始数据的地位、作用不同,引入了权重的概念,用矩阵理论的方法建立了加权回归预测模型,并提出了权重确定的几种方法,最后以西安市货运量预测作为实例进行了分析与计算。

According to the difference of position and function of the primitive data in prediction,this paper puts forward the conception of weight coefficient,establishes the weight regression model using method of matrix theory,and puts forward a few methods to calculate weight coefficient.
