Re: Bayesian VAR
The BVAR addin doesn't support nonsimple (i.e. 17) lag structures.

hi Gareth,
thks for the reply.
but can anyone teach me where should i change or tinker from becasue i cant seem to get the lag lag correct in program code and sub routines. can i have a look of how VAR source code looks like to change the BVAR one?
tyrying to make it more operational. Im gg from Matlab to Eviews with all these. cheers to developers.

VARs are not addins like BVARs  they are not written in an EViews program.

hi Gareth,
thank you once again. that i know. just wondering is there a way i can get hold of VAR source code? clang?
or how can i finetune BVAR program code?
much much appreciated.

The smart EViews gives you an option, "Extract selected graph", by rightclicking on the IRF graphs.And whilst still on this subject (sorry!): is there any chance of having the IRF graphs display a +/ 1 (and/or 2) std. error band?
I will put it on my todo list.
Best,
Esther
Dear Esther,
Just a question about IRF confidence intervals. Is it straightforward to build them? Is it possible to have an update of the Addin which also includes the bands? This would be extremely useful (as already the BVAR addin is) for any central banker/ graduate student.
Thanks
Question Bayesian VAR
Dear all,
I am so greatful if anyone of you give me a hint on the following issues with respect to using the addin for BVAR
1. The SimsZha NormalWishart allows for the exogenous variables. The impulse responses are only for the endogenous variables.
Is there a way that I get the responses of the endogenous variables as a result of the changes in the exogenous variables?
2. Is it possible to recover the variance decomposition after the estimation?
Thank you so much for your help in advance.

Re: Question Bayesian VAR
None of them are available.
Re: Bayesian VAR
I have not been able to get the bvar add in to work at all. I continually get the error '_SH01' is not defined. I have tried changing the estimation period, the variables I used, normalizing the data, different priors but nothing seems to work.

Here is what I am working with now.

Installed the latest version of the BVAR addin, from the link on the first page of this thread (Eviews v7.2)
Imported some data from excel (real gdp , cpi, civilian employment, industrial production, etc) 19802012q1
clicked 'addins' > Bayesian Var
Entered the variable names in the endogenous section plus the following:
estimation period=1980q4 2011q4, lags = 4, calculate irfs, SimsZha NormalWishart
defaults on everything else.
Clicked 'ok'
get the screen with the simzha hyperparameters, just chose defaults.
Clicked 'ok'
I then just get an error described above

Re: Bayesian VAR
What are your endogenous variables? The error message indicates that there exists a near singularity problem.

Re: Bayesian VAR... please help
I think I’m having a similar problem.
I attached my workfile (work1 is after I did all the steps below, work is before).
I want to estimate a BVAR with the variables m, n, f, k, l and i with one lag, using the Minnesota/Litterman prior (and calculate impulse responses for 1020 periods).
So, after installing the BVAR add in and estimating a regular VAR, I opened the BVAR and wrote:
Endogenous variables: m n f k l i
(just like this, no commas)
Exogenous variables: I wrote nothing
Estimation sample 1990 2010
(it appeared as default because of the workfile specification, I suppose)
1 lag
Calculate impulse responses, 10 periods
Koko Minnesota/Litterman prior
Name: stef
The next dialog box appeared, I left everything as default and after clicking OK, it said “Syntax error” and a lot of new things (series, matrixes, a group) appeared in my workfile…
Could you please help me…
Thank you so much in advance!
(Needless to say this is part of project that I have to submit this Saturday…)
