Abstract/
Summary |
In this paper the multimodel partitioning theory (Lainiotis 1976a; 1976b; 1971) is applied for simultaneous order identification and parameter estimation of multivariate (MV) autoregressive (AR) models. The simulations show that the proposed meted succeeds to select the correct MV AR model order and estimates the parameters accurately in very few steps and even with a small sample size. The results are compared to many other well established order selection criteria, namely Akaike's Information Criterion (1969), Schwarz's Bayesian Information Criterion (1978), Hannan's and Quinn’s (1979), Brockwell's and Davis' (1991) and C. C. Chen, R. A. Davis and P. J. Brockwell order determination criteria (1996). Finally as an extension it will be shown that the algorithm is also successful in tracking model order changes in real time. |
