| 中文摘要: |
| 本文目的是介绍与路径分析有关的基本概念、计算方法、两个实例及SAS实现。基本概念包括显变量与潜变量、直接效应与间接效应、路径图、路径模型与路径系数；计算方法涉及路径分析的数学模型及假设条件、路径分析中的具体计算；两个实例中的资料分别是“护士组织公平感与情商等六个项目间的相关系数矩阵”和“家庭、学校与学生的抑郁症数据的方差协方差矩阵”；借助SAS软件，对两个实例中的数据分别进行了路径分析，对SAS输出结果做出了合理的解释。 |
| 英文摘要: |
| The purpose of the paper was to introduce the basic concepts, calculation methods, two examples and SAS implementation related to the path analysis. Basic concepts included explicit variables and latent variables, direct effects and indirect effects, path diagrams, path models, and path coefficients; the calculation methods involved the mathematical model and assumptions of path analysis, and the specific calculation in path analysis; the data in the two examples were "correlation coefficient matrix between six items including nurses'' sense of organizational fairness and emotional intelligence " and "variance covariance matrix of family, school and student depression data"; with the help of SAS software, the path analysis of the data in the two examples was carried out, and an explanation was made for the output results of SAS. |
