Re: Filepath metadata in EViews databases

It's not really the database - it's that EViews objects often contain information about how they were generated in a 'history' section in the label view of the object. (Choose View/Label from the series menu to see a table containing the descriptive information attached to a series). You'll also see...

Re: Problems with data

What's going on is that the numbers in the spreadsheet are actually Excel string values eg. "27,71" not Excel numeric values and EViews is converting them into numbers assuming that the period is the decimal point character. I'm looking into whether we can improve this, but it will always ...

Re: Define lead/lag via @month or @quarter

Good news and bad news on this one... I've fixed the evaluation of x(-@month) in a standard series evaluation so that it should work correctly. Should be fixed in the next patch we release. The bad news is that you're still not going to be able to use this expression in models. We don't allow variab...

Re: Find a special day each month

Here's one approach. First calculate the first Wednesday in each month: series firstwed = @recode(@weekday>3, @date+(10-@weekday), @date+(3-@weekday)) Then add on two weeks to get to the third wednesday: show @datestr(firstwed + 14, "Weekday Month day year") I'm taking a bit of a shortcut ...

Re: Solving VAR Model - Innovation Generation Option

Lots of statements in your post, which I think basically all sound correct. Here are some comments: Normal Random Numbers: Yes. We draw normally distributed random numbers for the epsilons with a distribution that matches the covariance of the observed pre-forecast residuals (or the covariance obser...

Re: Copying data from one dated panel to another

Unless I'm missing something, couldn't you just generate an extra series in the first panel containing only the country code for each observation and then match merge in the series from the second panel using the new country series as the destination id series? You should be able to use any series y...

Re: FEVD estimation question

I'm not sure I understand exactly what you are asking. The variance decomposition numbers are expressed as percentages of the total forecast error variance within the period. I'm not sure what you are refering to by 'shock values' in this context. What different possibilities did you have in mind fo...

Re: Coefficient uncertainty in stochastic model solve -- log

You'll have to include the equations as links in the model instead of appending their text specification. The text form for this is a colon followed by the equation obejct name, Interactively, you can drag and drop the equation into the model. In a program, use the model.merge command. In your case ...

Re: Coefficient uncertainty in stochastic model solve -- log

Could you be a bit more specific about exactly how you have things set up inside EViews? When coefficient uncertainty is included in a simulation we generate a random draw for the coefficients at the beginning of each iteration. The draw follows a normal distribution using a mean and variance that m...

Re: Coefficient uncertainty in stochastic model solve -- log

I'm actually not sure what the documentation has in mind when it warns you about "nonlinear equations". I stepped through the code and I can't see any difference in behaviour whether the estimated equation has a linear or non-linear specification. Either way, we pull new values of the coef...

Re: data read in (easy question!)

The differences you are seeing are due to the contents of row 11 in the sheets. In the pages DUMMIES and OTH this row is completely blank. In the sheet HI this row contains a value. It matters because EViews considers blank lines as separators between different sections of the sheet (tables, heading...

Re: Possible issue with rounding third decimal place

Here's a bit more detail as to what is going on. Most decimals aren't exactly representable in the format that is used to hold numbers within EViews (IEEE double precision floating point). This is because IEEE floating point uses a power of two for the exponent of the number rather than a power of 1...

Re: Problem with the latest update of Eviews 8

I've looked over the file you sent but I'm still a bit confused. My best guess is that the difference in behaviour has happened before you get to the beginning of the program fragment you posted. If you look at 'View...Group Members' for the group g1 before any of the code you posted executes, does ...

Re: Proc/Make Graph in Model (EViews 8)

I believe the sample is defaulting to the current workfile sample (not the entire range of the workfile). Model solve also defaults to using the current workfile sample, so if you set the workfile sample to the range over which you forecast (by double clicking on 'sample' at the top of the workfile ...
