摘 要: 本文重点针对区域公路运输量的宏观预测问题建立了广义线性混合回归模型,以综合考虑运量数据自身变化的统计规律及其与社会经济变量的统计依赖关系。本文还设计了相应的算法及计算程序,以便实际应用与推广。 To synthetically consider the statistical regularity of independent change ofthe freight volume data and their dependency on socio-economic variables and particularlyaiming at the macro forecasting of regional highway freight volume,a generalized linearlymixed regression model is proposed in this paper.The relevant algorithm programed was al-so presented in the paper.
