And it’s called Confirmatory Factor Analysis (CFA) as we will, unsuprisingly, be seeking to confirm a pre-specificied latent factor structure. Hi all! Confirmatory factor analysis (CFA) is a multivariate statistical procedure that is used to test how well the measured variables represent the number of constructs. CFA = confirmatory factor analysis. Cite. It belongs to the family of structural equation modeling techniques that allow for the investigation of causal relations among latent and observed variables in a priori specified, theory-derived models. CFA allows the researcher to establish whether a pool of observed variables, underlying broader theoretically derived concepts, can be reduced into a smaller number of latent factors. … It offers standard analysis procedures in both their classical and Bayesian form.

Confirmatory Factor Analysis allows us to give a specific metric to the latent variable that makes sense. Green SB, Thompson MS. When the observed variables are categorical, CFA is also referred to as item response theory (IRT) analysis (Fox, 2010; van der Linden, 2016). EFA (left) and CFA (right). [1] In CFA, instead of doing an analysis where we see how the data goes together in an exploratory sense, we instead impose a structure, like in Fig. Filter the same ESS8 trimmed data so that there are only one country: Netherlands; Run CFA analysis using variables below. 4.5 out of 5 stars 10. The 12 … As such, CFA is used for several purposes including scale development and as a foundation for latent regression analysis and structural equation modelling (SEM).
