Re: GregoryHansen Cointegration Test
Dear brother,
Can you please tell me how to install the add in for gregory hansen cointegration in eviews8

Re: GregoryHansen Cointegration Test
This is not an addin. Just copypaste the code into a new program window and change only the part above the subroutine before running it.

Re: GregoryHansen Cointegration Test
Dear Mr. Trubador, thank you very much for sharing. Your post really help me in conducting my research. I really appreciate if you could also share on how to conduct the unit root test with break proposed by Narayan and Popp (2010) and Johansen, Mosconi & Nielsen (2000) cointegration test with break. You kind help is highly appreciated

Re: GregoryHansen Cointegration Test
I have found the program file for Johansen et al (2000) from Prof. Dave Giles website. However, I am not sure on how can I conduct the test. Hope you can help.

Re: GregoryHansen Cointegration Test
Please, I am new in using EVIEWS 9. I wish to perform the GregoryHansen ; and Hatemi J cointegration test . I have copied the codes stated above into the proceedure shown( File/New/Program). I have also edited to suit my variables. Now, what do i do next to run the following 1. Gregory Hansen cointegration test and 2. HatemiJ cointegration test.
Thank you.
Thank you.
Re: GregoryHansen Cointegration Test
Dear Trubador,
Assuming we do find evidence of cointegration, how would we proceed with our analysis if we had to estimate a VECM? How would the structural break or regime change be modelled in EViews? Would it suffice to simply split the sample into two subperiods and estimate two models?
I appreciate any guidance,
Kahn.

Re: GregoryHansen Cointegration Test
Would it be valid to use the GH test for multiple series at once?

Re: GregoryHansen Cointegration Test
Dear trubador,
I know NOTHING about subroutines on Eviews but i need to learn them for my master thesis. I am a student of Economics but unfortunately we didn't learn on time how to work on Eviews.
Basically, you wrote a subroutine for this GH test, that I need to apply to my timeseries variables. How can I do that? I mean, I should just substitute my variables putting them in your subroutine and then press "run". How to do that?
Thanks a lot, you can save me!

Probably the best thing to do is to learn about subroutines.

Re: GregoryHansen Cointegration Test
Hello Trubador,
Thanks very much for your code.
I'm using EViews 9 and I got the following error message:
"Near singular matrix error. Regressors may be perfectly collinear in "DO_ GHC.LS Y C (@TREND>92) G"
I've tested for different values of scalar Model (2 to 4); the same error message appears.
Please find attached my data and the program.
Many thanks!

Hello startz,
Thanks for your prompt reply.
Sorry, I can't grasp the implications of your answer. What should I do to fix the problem?
Best regards, Mara

Perhaps just delete that variable.
Re: GregoryHansen Cointegration Test
Hi,
I would like to know, how to apply Gregory  Hansen Cointegration Test using Eviews 10?
Taking into account that I have Y as the dependent variable and X1, X2 and X3 as the independent variables
Best wishes,
Salwan
