摘要
以腰果播种试验为例阐明通径分析的SAS过程,并通过标准化回归系数的方法计算通径系数。之后,进一步阐明相关系数分解为直接通径系数与间接通径系数之和。最后,对通径分析的结果作出全面的解释。
This paper discusses SAS procedure in path analysis of cashew sowing. Path coefficient is calculated by a standardization method of regression coefficient. The resolution to correlation coefficient is made by direct and indirect paths. Finally, the result of path analysis is explained all-sidedly.
