Re: transpose in a loop

Hello, Well that shouldn't be a happening. First, what is the version, build date, and bit architecture (32 or 64) of your copy of EViews? You can find all this information in the menu Help -> About EViews. Second, how large is the matrix that fails under @transpose? And finally, would you be able t...

Re: Bivariate model-long run restriction

Hello, I suggest you take a look at the Structural VAR section of the EViews documentation. A Blanchard-Quah style decomposition requires only a single zero restriction in the F matrix. Just keep in mind that you're performing a structural decomposition, so you're not producing shocks to your indivi...

Re: Obtaining group statistics (time x series)

Hello, @quantile can be applied to matrices, generating a quantile over all elements in the matrix (not to be confused with @cquantile, which generates per-column quantiles). This allows you to avoid stacking the data by creating a matrix from your group via stom() or @convert. For example, @quantil...

Re: breaking lines of code with " _ " in program not working

Hello,

Correct, the underscore character loses its special meaning for line continuation within a string literal. However, you can use a combination of string concatenation and continuation to achieve the desired result, e.g.,

Code: Select all

%test="One Two Three " + _
"Four"

Re: Strange behaviour with model

Hello,

That certainly sounds like a bug, but I have not been able to recreate the issue. Could you post an EViews program/workfile that demonstrates the problem?

Re: Extracting exclude dates

Hello,

I'm afraid there isn't a convenient model data member for retrieving the exclusion sample. I believe the only way to access that information programmatically is to freeze and parse the Scenario View table.

Re: panel workfile - random draw holding one dimension fixed?

Hello, The distribution sampling functions are not panel-aware, so you'll need to draw the random values for one period and then copy those values to all periods. For example, wfcreate(wf=panel, page=panel) a 2000 2100 100 for !s=1 to 10 smpl @first @first genr sigmad_{!s} = @rgamma(0.5,1) smpl @fir...

Re: Using add-factors as exogenous variables?

Hello, It is possible by modifying the model's text specification. The command that specifies the presence of an add factor in an equation, e.g., @ADD Y Y_A will accept non-"_A" names for the add factor series, e.g., @ADD Y Y_B After a few quick tests, this doesn't appear to break anything...

Re: Using add-factors as exogenous variables?

Hi Thomas, I agree that effectively having two sets of add factors per equation is cumbersome and error-prone. Working within the current limits of EViews' model object, I see two options for setting up the model as you desire. Both place an extra burden on the end-user, you can judge if the burden ...

Re: compare script version comparison

Hello, I'm afraid EViews does not include that sort of program difference functionality, but there are plenty of third-party utilities specifically designed for that task. WinMerge is one such application that comes to mind, but there are many others. No doubt Google can point you in the right direc...

Re: PERCENTILE

After a quick empirical check, it appears that Excel is using the van der Waerden interpolation method. That isn't the default interpolation method for EViews, but it is available, e.g.

Code: Select all

scalar perc_rprice=@quantile(exceldata,0.01,"v")

Re: minimum of constrained nonlinear multivariable function

Hello,

There is not. Constrained optimization in EViews must be performed by variable transformation.
