Hi,

I read in "https://es.mathworks.com/products/sysid/?refresh=true".
 "The toolbox provides identification techniques such as maximum likelihood, prediction-error minimization (PEM), and subspace system identification"
And in other page "https://es.mathworks.com/products/sysid/features.html".
"Autoregressive (ARX, ARMAX), Box-Jenkins, and Output-Error model estimation using maximum likelihood, prediction-error minimization (PEM), and subspace system identification techniques".
But I have not found the option to choose a single model ( ARX , ARMAX , OE ) between LS , PEM or ML .
I only found that the ARX model is estimated with the ARMAX and OE LS models with PEM and I find that so it can be used in different models ML.
Can you tell me how I can estimate the parameters of different models ( ARX , ARMAX , OE ) with different methods LS, PEM, ML?. In GUI and/or line comander.
I already some certain conditions are equivalent.
