I am currently trying to estimate an SVAR with sign restrictions, based on the program by Ouliaris and Pagan (2016). I modified it to make it work with my data. But, when I am running the program I got the following error message:
Singular matrix in "EQUATION INSTR_CPI.TSLS (US_CPI -
PATTERN_A(2,3)*USTB_RATIO - PATTERN_A(2,4)
*US_SHADOW) US_GDP US_GDP(-1) US_GDP(-2) US_CPI(-1)
US_CPI(-2) USTB_RATIO(-1) USTB_RATIO(-2) US_SHADOW(
-1) US_SHADOW(-2) C @ E_GDP US_GDP(-1) US_GDP(-2)
US_CPI(-1) US_CPI(-2) USTB_RATIO(-1) USTB_RATIO(-2)
US_SHADOW(-1) US_SHADOW(-2) C".
And I don't really see how to solve the problem...
In attachments, the program and the data.
I am working on EViews 9
Thanks to you all !
