In running a latent change score model, I receive the following error:
WARNING: THE LATENT VARIABLE COVARIANCE MATRIX (PSI) IS NOT POSITIVE DEFINITE.
The correlation matrix of latent variables as seen using TECH4 shows that correlation of one of the latent variables and all others is undefined (999). What does this mean?
