Re: Is there a solver tool?

I tried with the add-in irrval, but i could not programmed it. Does anybody knows if i can code an add-in? Or how can i use it in a loop? Thanks Each add-in comes with the help file, where author explains its use in detail. You can find the document in the add-in's folder-> C:\Users\...\Documents\E...

Re: Is there a solver tool?

Hi I too failed to manage to use the command-line version of irrval. Tried both the global command, and the series version. Irrval(series=«seriesname») Irrval(«seriesname») Irrval(seriesname) (And with versions like scalar test = …. Any of the above). Seriesname.irrval(results) Since the menu -alte...

Null hypothesis in the omitted variables test

I believe the null hypothesis in the omitted variables test should either read "..are NOT jointly significant..." or "...are jointly INsignificant..." wfcreate u 100 series x1 = nrnd series x2 = nrnd series y = 2 + .8*x1 + 0.2*x2 + @rnorm equation eq1.ls y c freeze(omitted) eq1.t...

L1FILTER

This thread is about l1filter add-in. The add-in allows you to extract a piecewise linear trend by primal-dual interior point method proposed by Kim et al. (2009). It is an alternative trend estimation method to well-known Hodrick-Prescott filter, but can also be used in determining the break (kink)...

Re: EViews 10

I am not sure if the seed option would be enough to produce random subsets for k-fold CV as each set should hold unique values of the total sample (e.g. draw without replacement). It should be clear that the code above does not ensure this property.

Re: EViews 10

I think OP refers to me as the "author" who put the effort in writing the k-fold CV subroutine: http://forums.eviews.com/viewtopic.php?f=23&t=12261 I already shared with him the code behind this routine and totally agree that such approach (i.e. cross validation) should be made availab...

Re: Root Mean Square Error in Forecasting

That's the way how RMSE (or any other evaluation metric) is computed. There is nothing inherently wrong here. Whether or not to keep insignificant variables in the model is up to you (based on the research question, hypotheses and other statistical criteria of course).

Re: DCCGARCH11

Hey, So right now I am estimating bivariate dcc garch (return in 2 indices such as s&p500 and klse). Some of the paper that I read, define the mean equation such: r_t=γ_0 + γ_1 r_(t-1)+ γ_2 r_(t-1)^us + ε_t ( I attached the paper's method and result) , it uses ar(1) process in the mean equation...

Re: HDecomp (historical decomposition)

Hi Trubador, When using the historical decomposition, I am looking to identify the SVAR using the Choleski Decomposition which you have provided However, there does not appear to be any place to provide the casual ordering necessary to identify the SVAR using the Choleski Decomposition approach.

Re: RunsTest

From the documentation that comes with the add-in: Analysis returns a vector of two values. First value corresponds to the number of runs and the second value represents the associated p-value. As for computing the z-stat: You can exploit the following relationship: scalar zstat = @qnorm(1-pval/2)

Re: TARCOINT

TARCOINT add-in is now updated to version 1.1 as of June 23, 2016.

Fixed a minor bug causing momentum option not to work properly when using the command line syntax. Supporting files are provided to guide users through some post-estimation analyses.

Re: Interpreting impulse response functions: Std dev or % ?

In the first case, the interpretation of the impact should be in percentages since the response variables are all in logarithms. One SD shock to UNCER leads to a 0.004 units decrease in the logarithm of LIP after 6 months, which corresponds to 0.4% drop in the LIP when translated into original level...
