Re[2]: Covariance: Matrix=S or Matrix=R

It could also indicate that the model is overparameterised. Try using a more simple model (in either structural or statistical aspects). S-matrix usually runs easier, but this does not mean you can always trust it. However, Im not an expert on this, so I cannot tell you whether your estimates represent the best fit. If you shared some of your data and control file with the group, maybe somebody else might be able to help you. Nele Plock
