I have fit two saturated models and have created correlation matrices from the expected covariance matrices using the cov2cor function. I would like to constrain the correlation matrices to equality between these models without constraining the covariance matrices.
I have tried adding a mxConstraint object to the combined model but I get errors and I am not able to constrain them by equating labels, as far as I can figure out. I'm just wondering if anyone has done anything like this? I'm sure I'm missing something very simple - I am brand new to all of this so the learning curve is a little steep at the moment.
Thanks!
