Some subspace procedures make use, directly or indirectly, of Vector AutoRegressive with eXogenous inputs (VARX) models in a preliminary step. This was first noticed for the CCA method; more recently it has also been proved that the first oblique projection step of a subspace algorithm based on predictor identification (PBSID) is asymptotically equivalent to the SSARX algorithm by Jansson which performs a preliminary VARX modeling step. For the purpose of comparison with more classical methods… CONTINUE READING
