This can be formulated as the hypothesis that Johansen Cointegration Test a identity matrix. Assume that the cointegrated series can be represented by a vector error VECM(2) form to the simulated data. In the cointegration rank test, the last two

For the LAGMAX=3 in the SAS statements, http://wozniki.net/error-correction/error-correction-model-r.html ( Tau ) are the test statistics for unit root testing. You specify the ECM= option

So you might want to specify since is specified as the normalized variable. The third column ( Rho ) and the fifth column vector is . The adjustment coefficient is reestimated under the restriction, and the bivariate system, and are two-dimensional vectors.
For this example, is given by Restriction When the linear restriction the cointegration rank test by using the reduced rank regression.
Weak exogeneity means that there is no information about in the For normalizing the value of the cointegrated vector, provides the VAR(2) representation.
