If both are constant over time, then the series … Webbvecrank— Estimate the cointegrating rank of a VECM 3 vecrank implements three types of methods for determining r, the number of cointegrating equations in a VECM. The first is Johansen’s “trace” statistic method. The second is his “maximum eigenvalue” statistic method. The third method chooses rto minimize an information criterion.
Webbrelations, then you can run the VECM by doing OLS of Yt on lags of Yand ’Yt 1. - If you know nothing, then you can either (i) run OLS in levels, or (ii) test (many times) to estimate cointegrating relations. Then, run VECM. • The problem with this approach is that you are testing many times and estimating cointegrating relationships. WebbVECM tests. Further inferences are then made based on the VDC and IRF analysis. Finally, section 4 concludes and draws several policy recommendations from the major findings …
