It seems that this is specific to the model you're using. Because I tried it on my end, and the model I was using solved successfully both times. Strange!

Well, one idea: in X-13, you can switch the model estimation method to "additive" rather than multiplicative. Then, values of zero won't be a problem (NAs are still an issue). The downside is that you may get a negative value in 2020m4 and 2020m5, but then you could overwrite that to zero.

Well, first you have to decide what you'd do in practice if there's only one month of data (or two months, etc..). If there's just one month of data, you can't use the same equation since you'd have NAs in the explanatory variables. (for example, there might be no data for "monthly\x1(-1)"...

I agree with this. I think essentially what he/she is saying is that the forecasts generated when you run the forecast evaluation are dynamic (rather than static) forecasts. This is problematic for equations that use lags of the dependent variable (which most forecasting equations do). For example, ...

Maybe Matt has a better method, but logically, when you get an error like that in a model, it must mean one of two things: 1. There's an exogenous variable with no data over the sample period, or 2. One of your endogenous variables is a function of its own lag, and there is missing data in these lag...

That's pretty useful, thanks for sharing, and I hope the EViews crew make it built-in, eventually.

Honestly, it's going to be extremely difficult to measure something like emissions' impact on health care costs, irrespective of the estimation technique. I'd look for a natural experiment here, rather than a time series estimation. But anyway, I think your conclusion that the results are inconclusi...

I confirm that I can replicate this crash in EViews 12 as well.

I second that request. The Fair-Taylor algorithm is not ideal for large macro models with MCE expectations (i.e. many leads), so incorporating the FRB/US algorithm would be a great addition to the EViews solvers.

Hello, It would make EViews graphs much more useful if we had the ability to apply different fonts and text coloring to different parts of a text in graphs. For example, if my graph title is "Chart 2: This is a title", I may want to have "Chart 2" in bold or in a different color ...

Hello, If I'm not mistaken, stacked area charts in EViews don't have the option to stack positive and negative values separately, in the same way that the option exists for stacked bar charts. With stacked bars, we can use the "stackposneg" option to achieve this, but it doesn't seem to ap...

It's possible to do this, but not easy. It can be done by imposing restrictions on the coefficients in the "VAR Restrictions" tab. Essentially, you need to 1) add the exogenous variables as endogenous variables, and 2) make sure that, for the equation for the exogenous variable, all the la...

When you select analytic, it gives you +/- 2 standard errors. So, that's usually close to a 95% confidence interval (but not exactly).

I don't think it's possible, unfortunately. But you're right, this would be a nice feature to add in future versions.

I second these very good suggestions
