多元门限回归模型优于单纯多元回归模型
Multivariate Threshold Regression Method Is Better Than Multivariate Regression Model
利用乌江渡1951-2006年月径流量和74项气象因子资料拟合,建立单纯的多元回归模型和非线性多元门限回归模型,对2007、2008年月径流量进行预报以检验效果。结果通过精度检验,可用作预报。非线性的多元门限回归模型更接近水文资料的实际状况,无论在拟合还是预报方面均优于多元回归模型。
he paper uses the Wujiangdu monthly runoff and 74 meteorological factors data in 1951-2006 to establish the multivariate regression model and multivariate threshold regression model. Based on the model, test is carried on using the data in 2007-2008, with high accuracy and stability. The non-linear method is closer to the real changing trend of the hydrology elements, which is better than the simple multivariate regression model.
