Re: Problem with Time Varying VAR

Dear Tom,

Thank you very much for your answer. I understand, by the Lutkepohl example, that I should estimate the TVAR equation by equation using DLM. Am I right?

Best regards,

Fructuoso

Problem with Time Varying VAR

Dear all, I have been writing a Time Varying VAR code in RATS by using Carter Kohn algorithm, but I am getting a really bad result from it. When I do the first step of the algorithm, drawing BT from a normal distribution, I use %modelsetcoeffs to put BT into a VAR in order to check the stability, I ...

State space models with constraints

Dear all, I am trying to impose constraints on the states of a state space model, like in this paper (page 16): https://www.piie.com/publications/wp/wp15-19.pdf In there, the sum of the parameters -states- of inflation backwards and forwards are equal to one. I was trying to impose a constraint of t...

Problem with dynamic zero restrictions in a VAR

Dear Tom, I would like to ask you a question regarding zero restrictions by using @irfrestrict. I am trying to make zero a series of IRFs, but my problema is the following: I can zero'ed without any problema until the four period, but if I try to increase the number of zero shocks for more periods, ...
