Re: Time varying SVAR
Hi, I am trying to look at the impact of real rates on the unemployment and cpi, but is giving error Near Singular Matrix, I can,t log the series as these have negative values as well and also these are rates. Can you please help ?

Re: Time varying SVAR
you have the multicollinearity problem. the correlation coefficient is almost minus one between real rates and cpi

Re: Time varying SVAR
Yes, you are absolutely right, actually the CPI and unemployment are dependent variables and real rates are independent variables, so in simple regression it should not be the case of multicolinarity. Can you please suggest me how I can solve this issue in TVSVAR ? Thanks again for help.

Re: Time varying SVAR
Ali,
Unfortunately, all variables are dependent (endogenous) variables for TVSVAR. There is no independent (exogenous) variables except constant. Instead of TVSVAR you should consider TAR model.

Re: Time varying SVAR
Hi,
I am wondering what will be the size of V Matrix if I have 4 instead of three variables ? will it be the same as mentioned in the document or will be add extra row or column ? Please guide.

Re: Time varying SVAR
Please reply to my previous message, I want to include 4 variables instead of 3. If needed how I can add into the V Matrix equation given in the document?

Re: Time varying SVAR
If you choose 4 variables then the size of V matrix would be 4x4.

Re: Time varying SVAR
Thank you very much, what about At the lower triangular matrix, given that we have 4 variables and also a constant, would it be 5 x 5 or 4x4?

Re: Time varying SVAR
Hi. I've reviewed the postings on the TVSVAR addin. Very helpful, thanks. two issues:
1. I could not find the example data.
2. I'm using EV 9.5, my data runs from 2001m022016m02. I chose 2004m02, 2009m02 and 2016m02 for my date selection vector, no commas. I am getting the error message" Matrix vector index out of range." I noticed you already explained this on the forum!! Any ideas? Thanks much. Best, Bahram

1. For example C:\Users\...\Documents\EViews Addins\TVSVAR
2. Could you post the data?

Re: Time varying SVAR
Hi. Thanks much. Please see my worksheet copy
. I'm using the pc version of the variables, i.e., %change. I copied the page of the workfile so that you can even see the results I got after the error message. Appreciate any insights. Thanks much. Best, BWho is online
