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).

lavaan WARNING: covariance matrix of latent variables but lavInspect( fit, "cov.lv") are all positive,what's the problem?

Adding that your factor correlations are very high across the board. The lowest one I spot is .76.

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.
