I thought you were referring to this, which is why I added the "keep in mind" to my reply Dy = A0 + P1.Dy(t-1) + P.y(t-1) = A0 + P1.Dy(t-1) + A.B.y(t-1) B is not identified, meaning that P = A*.B* = (A*G).(Ginverse.B*) = A**.B** P can be decomposed into an infinite number of A's and B's One identification rule is to set B = [I B2] where I is the unit matrix Since I is set it is not estimated and, therefore, has no standard errors and the like. In your output extract below, the column Coef is giving you the first row of B: 1 0 0 0 -.046 .013 The e-15's and e-17's are just zeroes.

Why is there no Std. Err. etc. for lnbrd, lnfrd, ... ? And still, I don't really know how I could make an ECM out of the VEC results.
