Nested covariates in latent profile anaylsis

Hello!

In preparation for project week, I was wondering if anyone knew how to control for covariates, especially multi-level nested covariates (like family and site in the ABCD dataset), when running a latent profile analysis (LPA) in R.

I saw that M-plus seems to allow for the inclusion of nested variables by adding TYPE=COMPLEX TWOLEVEL MIXTURE to the model. However, we were planning on using the tidyLPA R package rather than M-plus, or other proprietary software.

So we were wondering if it is possible to run a model like this in R? Additionally, could one possible work around be to: regress out the effects of covariates on input variables before hand and run the LPA on the residuals?

Thanks so much for your thoughts!

Hi jFlannery
Did you find an answer? I also wondering how to add covariates in a LPA analysis.
Thanks!
