Re: Importing matrices from Matlab

1.) save it as a .txt or .csv from matlab 2.) create your workfile in eviews (be sure it has the correct structure and size) 3.) file --> import --> matrix from file 4.) if your variable of interest is the fourth column of your matrix X, do something like: myvariable=columnextract(X,4), mtos(myvaria...

Tips or tricks for a specific element by element operation

Dear all, I was wondering if anyone could provide any tips or tricks to speed up the efficiency of the operation of element by element operations. Please consider the following short program as an example: wfcreate u 1 'preamble to set up the question !size = 100 'preamble to set up the question mat...

Re: Matrix Capacity

I'm running 64bit EE on this system, which is just curtailed by RAM size. I bet if you changed 10000 to ~16000 and let it run for a few hours, you'd see the same crash even with 64gb of ram...

Re: Matrix Capacity

Interesting crash bug: when i just tried to create a second (large) matrix to test near to the limit, i got a 'stopped working' message. Undoubtedly due to the fact I'm on a 4gb laptop only, but a warning message might be cooler than a crash bug :P As a test, I then ran: wfcreate u 1 for !a = 1 to 9...

Matrix Capacity

Dear all, Could somebody possibly provide some details on the maximum permissible number of matrix elements? Cant see any information on http://www.eviews.com/EViews9/ev9capacity.html? It seems a 625m element matrix is too large. I guess I could write a short program to sequentially test the boundar...

an old favourite

Dear all,

If memory serves, an old crash bug has potentially resurfaced:

Code: Select all

wfcreate u 1
scalar oldbug = thismatrixdoesntexist(1,1)


Best wishes as always!

Alternatively, you could use this code below which I just knocked up as an example if you wanted to write your own.... :D wfcreate q 1975q1 2000q1 genr x = 5+@trend+5*@nrnd genr y = 5+@trend+5*@nrnd genr z = 5+@trend+5*@nrnd %adjgroup = "x y z" group seasadjust {%adjgroup} for !i=1 to seas...

Re: MacroTrans

Hi Anyango! This is a great question and one I anticipated. The answer is because in a lot of the larger macro-panel style datasets that this add-in was designed to be used in, they will usually be series such as interest rates, bond yields, or similar. In these instances, typically, you dont want t...

MacroTrans

This is a thread to discuss the MacroTrans add-in. The addin operates on group objects from either the command line or group proc, automatically adjusting group members (series) one at a time in convention with the prominent macroeconometric literature. Designed for quarterly or monthly workfiles, i...

Re: DMtest - Diebold-Mariano Forecast Evaluation Test

Out of interest, was there a conclusion as to why this add-in was programmed to take in equation objects and not just forecasted series and dependent variables? seems a slightly strange choice to me... edit: it also seems strange that this version of the addin makes no HAC correction, when doing so ...

Re: Crash problems Eviews 9

Not sure if this is the same bug (todays build), but when im trying to .makemodel on a VAR object which doesnt exist (in a large series of nested control statements), I get an undetermined crash bug. Could be specific to this build or earlier, but not encountered it before.

Re: Generating monthly data from annual/quarterly data

As a suggestion, claiming only the vaguest, most minimal expertise in this field, you could estimate a SARIMA model from one of your monthly series and use the coefficients to interpolate your quarterly/annual.

Re: Var & Vecm, please help me.. Eviews 7

1.) Your method is correct. It depends what IC you want to put more faith in. Ultimately these are both just results to guide whatever theory you have about the relationship between the variables. There are a large, large number of extensions from this basic framework to analyse whether there exists...
