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.

Robust T value in Lavaan R

Is there any way to get robust t-value for the factors in lavaan when using confirmatory factor analysis with the function cfa() and structural equation modeling with function sem()? Is it the same as the z-score when using summary(fit,…

Pulling out modification indices for variances of items with lavaan in R

I've run a Multigroup CFA model with the package 'lavaan' in R and found that when running the strict invariance model the two groups were not invariant (not equal). This suggest that at least on one item the range is not the same for the two groups…

How to specify different model for certain groups in multigroup measurement invariance in lavaan?

I have a dataset in which some, but not all, subjects participated at Time 2. I want to run a measurement invariance analysis across time and across groups. Of course, for those who participated at Time 1 only, Time 2 latent variables would not be…

Empty cells warning and missing robust fit measures with WLSMV

I'm trying to fit a model with ordinal variables and it seems like, due to a sample size of just N=111, there are quite a lot of empty cells in the correlation tables: fit <- cfa( model = my.model, data = items, ordered =…
