I am encountering a problem in running a model that includes the interaction of two latent variables. I received the following message:
THE ESTIMATED COVARIANCE MATRIX COULD NOT BE INVERTED. COMPUTATION COULD NOT BE COMPLETED IN ITERATION 1. CHANGE YOUR MODEL AND/OR STARTING VALUES.
I have checked my model and tried different starting values, but neither strategy has been of avail. One of the latent variables is defined by only 2 indicators and the other by 4 indicators - could this be part of the problem? Any ideas?
