Sorry for the confusing description. I just want to construct a negative initial shock. The above code gives positive change, and I want to make it negative.

Hi, I'm looking at the code and was wondering what I should do if I want to implement a negative interest rate shock. Thanks.

Thanks so much for your timely feedback. I really appreciate it. Actually I tried to make interest rate the shock, and that's the third variable in my system. I made some changes to make it easier to read. compute [vector] rate=%xcol(faclast,3) In this case, if I want to make sure the fourth variabl...

Thanks for the quick response. I changed my code according to your suggestions. Two questions came up as follows. 1. It seems the response of the interest rate to itself is still negative. 2. The results I get from the Covariance Model-Likelihood - Estimation by BFGS is local optimum, not global opt...

Hi, I'm new to RATS and now I'm trying to replicate the Cushman and Zha (1997) paper for a course project. I had a relatively large dataset, but for simplicity, I chose the first five domestic variables and two exogenous variables from US. I read the original code of the paper and tried to find answ...
