Re: Model computational Limits?
My pleasure. While not exactly the debugging path I followed, this particular type of issue would be revealed via a simple visual scan of the exogenous data for NAs. The model "Proc -> Make Group/Table..." procedure is convenient for quickly generating a group of just the utilized exogenou...

Re: Model computational Limits?
Hello, It turns out this is a run-of-the-mill missing data issue. In model MOD_PNT2, the equation for variable CO2_A_0MB references exogenous variable CPI_12(-1). Unfortunately, that series doesn't contain data (only NAs) after 2023M11, thus there's going to be a problem in 2024M01 as you've experie...

Re: Model computational Limits?
Hello, Given that there are no missing values in the data and that simpler variations of your model solve successfully, my first thought is that the full model includes some type of numerical issue that only the data for that one observation happens to trigger. I would certainly like to examine your...
Re: FLIPTYPE
Hello, The algebra performed by the fliptype procedure doesn't consider special cases when inverting functions, e.g., introducing a potential for division by zero where none existing previously. In general, the procedure will just attempt to "solve for" the leftmost instance of the new end...

Re: @recode issue
Hello, The issue is the expressions used in the @recode statements for AFG_80, AFG_70, and AFG_60. You cannot test whether a value is within a range using an expression such as "X80 <= AFG < X90". Instead, use two conjoined relational expressions, i.e. "X80 <= AFG and AFG < X90",...

Re: sample adjusted
Hello, The model solution procedure adjusts the solution sample to ensure that all referenced variable lags/leads exist in the workfile. For example, imagine a quarterly workfile spanning 2000Q1 to 2020Q4. If the specified solution sample covered the full workfile, "2000Q1 2020Q4", but the...

Re: addinit(v=a)
Hello, It's possible that if solution values (or expressions they appear in) are very close to numeric singularities, then the adjustment of add factors combined with the solution rounding and significant digits setting could produce such failures. Here's a small program that demonstrates this effec...

Re: scaled IRF in SVAR
Hello, Would that be error 82? It appears that the sirf add-in contains a bug triggered by generating the IRF for any variable other than the first. EViews 13 stops the add-in at that point, but earlier versions of EViews proceed as if the user had specified the first variable. I don't see an easy w...

Re: SVAR short and long-run restriction
Hello,
I believe the restrictions you've currently applied to the B matrix should instead be applied to the S matrix. The A and B matrices will then be unrestricted.

Re: If - Else code
Hello, You may also find it more readable/maintainable to use a vector to store the mapping between the value of !i and that of !bestlag rather than a sequence of @recode statements. For example, vector(21) bestlagmap bestlagmap.fill 12, 6, 2, 1, 2, 2, 1, 4, 1, 1, 2, 2, 11, 1, 4, 1, 11, 6, 1, 12, 3 ...

Re: Is there a solver tool?
Hello,
Take a look at EViews' optimize command, which is the general purpose command for user-defined optimization. It requires knowledge of EViews programming to use, but it's very flexible once understood.

Re: GENERATING RANDOM NORMAL DRAWS
Quick follow up... EViews' @rnorm function is parameterless since it returns draws from the standard normal distribution. You can adjust your genr statement accordingly, e.g.,
Code: Select all
series draws_errorvariance_CA_{%h}Y_{%c}_AR = @rnorm * @sqrt(errorvariance_CA_{%h}Y_{%c}_AR)

Re: @colpctiles Not Working...
Hello,
You're correct, the rank 'direction' argument is being incorrectly ignored. We'll fix that in an upcoming patch.

Re: Incorrect error message
The errors messages didn't directly implicate the variable, DISPINCRP, so a little investigation is necessary as random_user points out. The most significant clue comes from your description; the issue only arises in your custom scenario and not the default scenario. The model's scenario summary (Vi...

Re: Incorrect error message
Hello, EViews is correctly reporting that override data is missing in Scenario 2. That scenario excludes and overrides series DISPINCRP, but the series that should hold the override values, DISPINCRP_2M, is full of NAs. Perhaps that series didn't exist prior to your initial solution attempt and an e...
