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).
