Thanks again. I apologize for my silly oversight. Again, name a charity, if there is one that Eviews or you prefer. // Jim S.

Thank you so much, Matt. I'm abashed -- it was actually a coding error on my part in the System equation. I should have been referencing the generated inflation variables which do span the time frame, rather than the actual CPI variable that does not. I'd love to know how you debugged it so I can do...

Just a note, Matt. Following your initial thoughts on the problem, I tried simplifying the data entries for that one observation, 2024m01, by rounding them all down to integer values, down from the default 16 or so decimal places. But I got the same error message from running model MOD_PNT2 in Deter...

Thank you very much, Matt. Please find the file attached below. There's a lot of MODEL output (variable simulations in various forms), but the files I mentioned by name should all be there.

I should add that my copy of EViews 12 is the Enterprise Edition, Oct. 18 2023 Build. The data set is 13 columns of monthly data from 1973 to 2024 inclusive, or 13 x 52 x 12 = 8,112 data points. Therefore, it seems unlikely that the computational limits would have been exceeded. The SYSTEM object un...

I am using EViews 12. I have worked with EVeiws Systems and Model commands for several years now, but just ran into a problem I can’t diagnose. I built MOD_PNT2 from VAR_PNT2, then changing that to SYS_PNT2, which I then revised with exogenous taxes added onto the endogenous price terms. Running the...

The crucial thing turned out to be to exclude but not to override -- so that the original variable was preserved. Thanks again.

OK, thanks Matt & Random User. You've given me things to investigate. I think I will start by deleting all the DISPINRPI variables, and generating the original DISPINCRP variable anew, so it is cleanly created within this workfile. Thanks for your expertise.

Thanks so much, Matt. 2 further questions, please: 1) Where in the output or error messaging do you find this detail? Or is it from your knowledge of the program? 2) More importantly for me, in previous attempts, the *_2m data WAS generated by my scenario 2 override. But unexplained to me, this *_2m...

When I run model Mod_M22 in this file, it aborts with the message that there is missing data. But the monthly data set is complete from 1973 to 2019, which includes the period specified (2015-20190. The trouble seems to be with the scenario. If I run it without a Scenario, there is no problem.

OK, sorry -- everyone can ignore this little post. I figured it out. I can't "treat as exogenous" a variable via the Scenario function if it's already been defined as exogenous. That was my mistake.

I have used the Scenario feature in Models before, but am having trouble now. An exogenous tax variable, COAL_T120, is specified and the baseline forecast for the model works fine -- just as long as it is not fixed by the Scenario. But when it is fixed, I get the error message "COAL_T120_1 is n...

Thanks, very much, Gareth. That did the trick.

For others in a similar spot, I had to rewrite the System representation with a new stand-in for C, which I very creatively termed CC. I then used the command coef(n) = CC, where n was the length of my new vector. It all worked out well.

I am trying to refine a VEC model by estimating it as a System . Even though the VECM estimates almost instantly, I consistently get a size limitation warning when I try to estimate a System version of the same system, with the message that "751 is not a valid index for vector-series-coefficien...

I have a VECM-based stochastic Model that works pretty well in EViews 12 forecasting the effects of taxes on energy prices if I just 1) add a tax to the historic price series, and then 2) treat the new price + tax series as exogenous in the Model for the forecast period. But what I would like to do ...
