I am very sorry to disturb you at this time. However, I need your guidance on the additional long-run restriction in SVECs model.

I am finding it difficult to use the additional long-run restriction in the SVEC interface. For instance, a four-variable VEC model with one cointegrating vector requires additional 3 long-run restrictions with the 3 linear independent shocks to exactly identified the system. My questions are;

1) Is it possible to use the total SVEC gui to do the restrictions ?

2) If not, how can I use the matrix interface in the SVEC gui to impose the additional long-run restrictions.

3) Then, how can one place the long-run restrictions as it suite the researcher.

Thanks.
