484—Chapter 32. Vector Autoregression and Error Correction Models
If the restrictions are binding, EViews will report the LR statistic to test the binding restrictions. The LR statistic is reported if the degrees of freedom of the asymptotic x2 distribution is positive. Note that the restrictions can be binding even if they are not identifying, (e.g. when you impose restrictions on the adjustment coefficients but not on the cointegrating vector).
Options for Restricted Estimation
Estimation of the restricted cointegrating vectors b and adjustment coefficients a generally involves an iterative process. The VEC Restrictions tab provides iteration control for the maximum number of iterations and the convergence criterion. EViews estimates the restricted b and a using the switching algorithm as described in Boswijk (1995). Each step of the algorithm is guaranteed to increase the likelihood and the algorithm should eventually converge (though convergence may be to a local rather than a global optimum). You may need to increase the number of iterations in case you are having difficulty achieving convergence at the default settings.
Once you have filled the dialog, simply click OK to estimate the VEC. Estimation of a VEC model is carried out in two steps. In the first step, we estimate the cointegrating relations from the Johansen procedure as used in the cointegration test. We then construct the error correction terms from the estimated cointegrating relations and estimate a VAR in first differences including the error correction terms as regressors.
A Note on Version Compatibility
The following changes made in Version 4 may yield VAR results that do not match those reported from previous versions of EViews:
•The estimated residual covariance matrix is now computed using the finite sample adjustment so the sum-of-squares is divided by T – p where p is the number of esti-
mated coefficients in each VAR equation. Previous versions of EViews divided the sum-of-squares by T .
•The standard errors for the cointegrating vector are now computed using the more general formula in Boswijk (1995), which also covers the restricted case.
