Here, we see that the relationships between the three latent variables is small but positive–with scaled covariances of .41, .26, and .17. Confirmatory factor analysis typically identifies a single set of factors and tries to model the data in that way. Some of the papers describing mediation are among the top 20 scientific research papers cited in any domain. How is secrecy maintained in movie production? The lavaan tutorial Yves Rosseel Department of Data Analysis Ghent University (Belgium) August 2, 2020 Abstract If you are new to lavaan, this is the place to start. Why would a compass not work in my world? To learn more, see our tips on writing great answers. Vsl and text are correlated; maybe they really don’t belong as separate latent factors. We can test whether they differ significantly using the anova function, which also gives us AIC/BIC statistics. However, these probably only properly apply to independent factor models. There are many varieties of thsee that ego under many n strames; most commonly structure equation models (SEM), latent variable models, path analysis models, and specific applications like latent growth models. We can use an anova function to compare the two: Now, there new more complex model, which has more parameters and fewer DF,fits more poorly than the smaller model, so we would again prefer the 3-parameter model. Draw plausible values of factor scores estimated from a fitted lavaan model, then treat them as multiple imputations of missing data using runMI.
