Confirmatory factor analysis revealed that the 16-item scale adequately captures four major. When the observed variables are categorical, CFA is also referred to as item response theory (IRT) analysis (Fox, 2010; van der Linden, 2016). You would get a measure of fit of your data to this model. Specify an initial CFA model. Although related to EFA, principal components analysis (PCA) is frequently miscategorized as an estimation method of common factor analysis. share. JASP is a free and open-source program for statistical analysis supported by the University of Amsterdam. [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. New York: Guilford Press; 2006.
