摘  要:
以思茅松多元线性树高模型为例,应用通径分析方法对该模型中的共线性进行了分析,并对比分析了相关系数分析方法和条件指数、容限度与方差膨胀因子判定方法。研究结果表明,通径分析方法不仅能判断林业多元线性模型中是否存在多重共线性,而且还能判断其多重共线性的不同来源和强弱;相对于常用的多重共线性检验方法,通径分析方法更具优越性。

摘  要:
Taken height-diameter multiple linear model of Pinus kesiya var.langbianensis as an example,the collinearity in this model was analyzed by using path analysis method.Moreover,path analysis method was compared with other analysis methods such as correlation method and the method of condition index,tolerance and variance inflation factor.Study results showed that path analysis could determine both whether there were multicollinearity and the sources and intensity of multicollinearity.Compared with the commonly used methods of multicollinearity test,path analysis methods showed more advantages.
