Welcome to the lavaan discussion group. Lavaan is an R package for latent variable analysis.

Note: the first time you post, it may take a while (a few hours, up to a few days) before your post is visible. That only happens the very first time you post, because one of the group owners needs to approve your post. (This is to avoid spam).

Please help me. Can I use a vcv matrix of factor scores as input to lavaan?

I have a covariance matrix from factor scores and I want to use that as input for my analysis.
