CFA is a validated factor analysis, which is used to test the reliability and validity of the scale.GFI, CFI, IFI are three kinds of fit indices, taking values ranging from 0 to 1, and the closer to 1, the better.RMSEA is recommended to be less than 0.08.The remaining two are the chi-square and the degrees of freedom respectively. Anyway, these are to evaluate the fitness of the model. Overall, the fitness of Google, Baidu and the overall model is pretty good. Anyway, there are a lot of statistical concepts in this, you learn the basic statistical principles first. There is no need to rush to touch these statistical software. If you do a paper on questionnaires, you should not consider this aspect of factor analysis, structural equations, etc. are too demanding for freshman students.
