WebOct 9, 2024 · Like EFA, CFA uses the common factor model, that is, it sees the covariance between observed variables as a reflection of the influence of one or more factors and also a variance that is not explained. This … In CFA, several statistical tests are used to determine how well the model fits to the data. Note that a good fit between the model and the data does not mean that the model is “correct”, or even that it explains a large proportion of the covariance. A “good model fit” only indicates that the model is plausible. When reporting the results of a confirmatory factor analysis, one is urged to report: a) the proposed models, b) any modifications made, c) which measures identify each lat…

Confirmatory factor analysis (CFA) starts with a hypothesis about how many factors there are and which items load on which factors. Factor loadings and factor correlations are obtained as in EFA. EFA, in contrast, does not specify a measurement model initially and usually seeks to discover the measurement … thrash artinya
