Abstract
Fixed coecients State-Space and VARMAX models are equivalent, mea- ning that they are able to represent the same linear dynamics, being indis- tinguishable in terms of overall t. However, each representation can be specically adequate for certain uses, so it is relevant to be able to choose between them. To this end, we propose two algorithms to go from gen- eral State-Space models to VARMAX forms. The rst one computes the coecients of a standard VARMAX model under some assumptions while the second, which is more general, returns the coecients of a VARMAX echelon. These procedures supplement the results already available in the literature allowing one to obtain the State-Space model matrices correspond- ing to any VARMAX. The paper also discusses some applications of these procedures by solving several theoretical and practical problems.
