Abstract

This paper presents an algebraic analysis using Matrix Padé Aproximation to improve the identification stage of the proposal in [6] on Scalar Component Models, specifically as it refers to the choice of a parameter they denote h. The original methodology in [6] is based on the construction and interpretation of a table whose elements are related to the singular value zero of certain relevant matrices in the process. We propose the alternative use of what we call a Ranks Table and the sure overall orders concept instead of the so-called overall orders. Ranks Table information allows for the improved interpretation and implication of the results and of potential computational and statistical properties.
