A free, open-source `R` package for latent variable analysis. `lavaan` includes support for a large variety of multivariate statistical models which contain (or not) latent variables. It allows multilevel analysis, and as estimators that deal with missing values and categorical data. Some of the applications available are confirmatory factor analysis, full structural equation models, latent growth curve models, and path analysis.
