Hello!
I'm working with the Systems Identification Toolbox. we are trying to estimate, using the PEM function.
I am receiving the warning : 'Covariance matrix estimate unreliable. Not stored.'
I would very much like to see the Covariance matrix... How should I start to troubleshoot this?
Thankyou!

Try to change the order of the estimated model.
