Discussion on ''On the Use of Minimal Parametrizations in Multivariable ARMAX Identification'' by R.P. Guidorzi
1999 (English)Report (Other academic)
When performing practical identication the structural issue often cannot be neglected since the conditioning of the parameterization inﬂuence the convergence of the optimization. Solutions are to carefully monitor the conditioning of the associated LS problem or to use alternative parametrizations (minimal or non-minimal) which give better conditioning.
