摘要
Abstract
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.关键词
