通径分析及其在林业试验统计分析中的应用

The Application of Path Coefficient Analysis and Its in Forestry Test Statistic Analysis

通径分析是在相关分析基础上，用来进一步剖分各性状之间关系的一种方法，它对了解性状间的因果关系及自变量对因变量的直接影响和间接影响很有帮助。本文简要地介绍了相关分析和通径分析的原理、计算方法，并例举了其在林业试验统计分析上的应用。

Based on relative analysis,the path coefficient analysis is a method which usedto subdivision the relation among the characters,it could help to understand the causationin direct effect and indirect effect of independent variable and dependent variable.This pa-per gives the principle of a brief introduction of relative analysis and path coefficient analy-sis,the method of calcaulation,also gives an example of its application in forestry statisticanalvsis。
