Based on Drubin-levinson algorithm,we deduced the coefficient for multivariate AR(p) processes,and we got the estimator by soluting the equation of Yule-walker.Then,we introduced the AICC criterion for order of the model.Finally,we made correlation analysis for practical problems using ITSM program.
