Notes: The numbers in parenthese is standard error, is the correlation coefficient, and , and are, respectively, the Akaike, Bayesian and Hannan-Quinn information criterion. and are, respectively, the 12th order multivariate Portmanteau tests for serial correlation in the standardized and squared standardized residuals (null Hypothesis: no serial correlation). The numbers in brackets are the P-values.
