I am trying to estimate a structural VECM on JMulti, but I am not able to get the estimation results.
I have a 7 variables model with three cointegrating relations (r=3).
I am setting three columns of zeros in the long run relations matrix (21 zeros, corresponding to 12 linearly independent restrictions). To identify the model, I need 21 total lin. indep. restrictions (7*6/2), three of which should go on the contemporaneous relations matrix. Well, once I add 6 zeros in the long run matrix and three zeros in the contemporaneous one, I am not able to get estimation results because an error message pops in: "Matrix is singular".
Is there a way to circumvent this problem?
Thanks in advance for your help.
I am also very curious to see any reply. but this forum seems to be dead :(
