Hello everyone !

I use the ARMAX model to analyze the time series through System Identification Toolbox

After working data with model, I get the model output which shows actual and estimated series.

However, I cannot get the prediction equation.

They only show A(q) equation (the difference equation)

Actually, I'm not really understand this point

How can I get the prediction equation of ARMAX model?

Please help me

Thank you all
