I am not sure if I will ever implement random effect models with ordinal data in lavaan. It would just be too slow (in R) to be practical. But Nick...

Thanks. That was helpful. I have not found papers/literature about this yet, but I do have some ideas how this can be done: when we compute the 'cluster robust' standard...

@sda030 Thanks. This document is about twolevel SEM with WLS. Unfortunately (as always with Mplus documents), they are a bit vague on the details. It might be feasible to implement...

No plans for the near future. But I will leave this issue open as a reminder.

I am afraid this is not a bug, but a (huge) misunderstanding. The residuals are based on the lavPredict() function, and the main purpose of this function is (and always...

5 years later, this is still not fixed. In that period, two people told me they would take this up, but nothing happened so far. It would seem I have...

Indeed. So maybe lavaan should just remove the standardized= argument in simulateData() (for now).

I have no explanation at the moment. I will investigate this later. But as an immediate solution, you can replace all '>0' constraints by ``` g =~ lower(0)*g_visual + lower(0)*g_cubes...

This may be platform dependent! I just installed R 4.1.1 on my Arch linux system, and it ran as slow as in R 4.2.1. The number of iterations were identical...

Full support for EFA has been included in 0.6-4. There is no dedicated function yet, but the following syntax can be used the with sem/lavaan functions: model
