H. Li et Rs. Tsay, A UNIFIED APPROACH TO IDENTIFYING MULTIVARIATE TIME-SERIES MODELS, Journal of the American Statistical Association, 93(442), 1998, pp. 770-782
This article proposes a Bayesian procedure for simultaneous identifica
tion of the Kronecker indices and model parameters of a multivariate l
inear system. The model parameters include the starting values and inn
ovations of the system so that the series considered may be co-integra
ted or non-invertible. The procedure uses some recent developments in
stochastic search variable selection in linear regression analysis and
Markov chain Monte Carlo methods in statistical computing. It also ta
kes into consideration the row structure of a vector model implied by
the Kronecker indices. Comparison with other existing methods is discu
ssed. Simulated and real examples are used to illustrate the proposed
procedure.
