Is it possible to use a correlation matrix as input for Lavaan? I have searched the web but was not able to find an answer. Many Thanks.

  • Welcome to stackoverflow. I'm afraid that we have too few information to help you. Could you please tell us more. What is Lavaan? is it a package in R is it in Rbase? What is your issue exactly?

The lavaan package is used to conduct latent variable analysis. While lavaan does support using a variance / covariance matrix as input to the procedure (see pp. 30 - 31 of the Lavaan tutorial for an example), it does not support use of a correlation matrix as input.
