WebMar 6, 2024 · Confirmatory Factor Analysis (CFA) We’ve seen above that while an EFA with 5 latent variables works great on our dataset, a structure with 6 latent factors might in fact be more appropriate. How can we statistically testif that’s actually the case? WebIn confirmatory factor analysis (CFA), a simple factor structure is posited, each variable can be a measure of only one factor, and the correlation structure of the data is tested against the hypothesized structure via goodness of fit tests. Figure 2 is a graphic representation of EFA and CFA. Figure 2. EFA (left) and CFA (right).

WebEFA/CFA could be similar/dissimilar depending on methodology 2. Orthogonal rotation is often used in the context of EFA, making the factors uncorrelated with each other. 3. In CFA the factors are usually allowed to correlate (i.e., oblique) 4. For this reason oblique rotation has started to be encouraged for EFA analysis. Webin a single run to make both EFA and CFA, some of them (eg 50%) can be randomly selected for EFA and the rest for CFA. Another way is to collect two different data sets and analyze one for EFA and the other for CFA. In adaptation studies, the use of EFA and CFA varies.
