Frequency Conversion

Hi, I have a quarterly model using quarterly averages of data, e.g., unemployment rate which is available in monthly frequency. Now I want to transform the modeled solution in quarterly back to its original monthly. If I have monthly data up to May 2016, how do I ensure that I will get the interpola...

Super add factors?

Hi gurus, Is there any option or plan to adopt the use of super-addfactors in the sense like this: - I want to impose a 1% increase in GDP by add factoring - GDP is sum of C, I, G, NX, so the imposing 1% increase in GDP means imposing 1% increase in all of its components. I think it's a tricky one i...

Re: EViews 8 crashed on [model].@overrides or .@olist

I still have issues with Eviews crashing when trying to use @overrides or @olist command. Not happening with @aflist or @exoglist.
Any suggestion?

Re: Find/Delete or Replace an equation in model's text form?

Great, I thought it didn't work with text. Now it's easier. Also, I think the command I will use is the model.merge to add the new linked equation object.
Thanks very much,

Re: Find/Delete or Replace an equation in model's text form?

Hi Gareth, I guess what I'm really looking for is to replace a text specification of an equation with a linked one so that we can easily find and modify it later in the process. I can write a code to replace all equations that have been modified by us in the GI US Macro model. However, it is often p...

Re: Find/Delete or Replace an equation in model's text form?

Got it work. Also, it seems like equations coefficients must be fully substituted to have it work properly if LHS has been transformed (i.e., log(sp500) versus sp500 originally)?
Thanks,

Find/Delete or Replace an equation in model's text form?

Hi all,

We used the GI US model for work. We did replace a few equations for own likings. However, we have to do the replacements manually every month when new GI forecast come out. Is there any way to program that part? We do have a fixed set of equations we'd like to replace.

Thanks,

Re: EViews 8 crashed on [model].@overrides or .@olist

I updated to Sept 12 build. Still have Eviews crashed once a while. Not sure what triggers it. Possibly problem with linked series.
Previous issue could be due to network drive sharing violation.

Re: Chow/Quandt-Andrews breakpoint test for VARs

I have tried that, getting system estimated. However, what I want is to perform the breakpoint tests Chow/Quandt-Andrews/Bai-Perron on the equations in the system. Is there anyway to handling individual equation in the system? I can run a loop and specify each equation from a VAR and test, but that ...

Re: Chow/Quandt-Andrews breakpoint test for VARs

How do you do a Wald test? I don't understand these steps. Let's say I have a bivariate VAR(1) of ffr and oilprice. I want to test if there is a break in each equation (1) ffr regression on lag oilprice and (2) oilprice regression on lag ffr. I want to put them into a program so that I can change/tr...

Chow/Quandt-Andrews breakpoint test for VARs

Hi, I understand that those tests are for equation only. If I'm interested in testing structural break in a VAR, equation by equation, what'd be the best way to do it? I'm thinking about breaking up a certain VAR into n single equations. What's the best command (makemodel or makesystem)? I'm having ...

Delete(noerr) not working

I have written a couple programs and this was a problem. Suddenly, now the error windows saying the object doesn't exist pop up. What's the solution?
