Multigroup SEM via lavaan

Maxim

Hello,

I'm attempting to do a SEM with three groups, assessing Measurement invariance at the same time. I use GUI function to constraint nothing (model 1 Configural invariance) vs. loadings (model 2: weak invariance) vs. loadings and intercepts (model 3: strong invariance) in a same model (i.e. structure) and want to compare the fits of the three models. But, JASP changes the selection of constraints each time I change it for one model, for all models. Hence, I end up with fitting the same model and can not compare them within JASP. Is it a bug or a lack of functionality?

Duplicate the analysis by clicking the green button and do it through separate analyses instead.

My guess is it's a "lack of functionality", as there are some scenarios where you want the constraints to be the same across models; this is just not as convenient for testing measurement insurance.
