中文摘要: |
本文目的是介绍与证实性因子分析有关的基本概念、计算方法、一个实例以及使用SAS实现计算的方法。基本概念包括显变量与潜变量、内生变量与外生变量、探索性与证实性、拟合优度、前提条件;计算方法涉及基本原理和数学模型、证实性因子模型的计算;一个实例的资料是“邓阜仙岩体样品的部分化学成分及其含量”;借助SAS软件,对实例中的数据进行了证实性因子分析,并对SAS输出结果做出了解释。 |
英文摘要: |
The purpose of this paper was to introduce the basic concepts, calculation methods, one example related to the confirmatory factor analysis, and how to implement calculations using SAS. Basic concepts included manifest variables and latent variables, endogenous variables and exogenous variables, exploratory and confirmatory, goodness of fit and prerequisites. The calculation methods involved the calculation of basic principles, mathematical models and confirmatory factor models. The data in the example was "partial chemical composition and content of Dengfuxian rock mass samples". With the help of SAS software, the confirmatory factor analysis was conducted on the data in the example and an explanation was given to the SAS output results. |
