Recursive dynamic forecasts

Hi all,

I have the same question as ylijohtaja. From what I can find, it seems that the recursive estimates under EViews' stability diagnostics functions are only available for OLS. Would anyone happen to know if there is a way to perform these functions for ARMA without having to write a programme?

Grateful for any help.

Thanks.
Ken

how to prevent eviews from deleting command?

When I type in the command, instead of pushing command text over like normal text editor, eviews overwrites the current command. Seriously why is eviews like that?

6. Do not overdo the caffeine
Of course it costs to open the eyes after so many hours in the dark. And yes, it's hard to think straight upon waking. You need coffee to start the day? No problem, but do not abuse. In the morning , do not take more than two (2) cups of coffee. A work day early and mid-morning (for example). The dependence of caffeine, caused by excessive consumption, cause descendants peak productivity and attention caused by the harmful effects that their absence has on our body.

7. Brush your teeth
It looks like a basic advice, does not it? But the fact is that we know that haste is the enemy of perfection and sudden waking causes many men not take account of the most basic care like brushing your teeth. Besides being to improve their oral health is improving its appearance and to prevent your breath make "magic (black)", setting it apart from others.

You do not need to make some variables exogenous forcefully. It is not good idea. You can use the confcast add-in.

Specifying indicators for frequency conversion

Hi!
I have an annual series for GDP which I would like transform into quarterly series. I have prepared two indicator series for the frequency conversion, however, when using Chow-Lin match-sum method, which should accommodate two indicator series, I get error message that specified indicator series does not exist. I am using Copy-And-Paste Special approach and in the indicator dialog I write: i1(first indicator) i2 (second indicator). Shall I place some separator between i1 and i2 so that Eviews can distinguish them?

Fama Macbeth Add-in

Hi,

I am trying to run a FM regression. My Excel file looks like this:

FirmIdentifier Year StockReturn ProfitRatio R&DRatio (and other variables)
1001 2009 8.56 ...
1001 2010 4.23 ...
1001 2011 -1.34 ...
1001 2012 -1.36 ...
1002 2009 2.45 ...
1002 2010 2.56 ...
...

In the FM Add-in I enter
List of portfolio/assets returns: StockReturn
List of factor names R&DRatio (just one example)
Put results into: results

Then receive the following error:
Near singular matrix in "ROWPLACE(G, @TRANSPOSE
(@INVERSE(@TRANSPOSE(DESIGN) * DESIGN) *
@TRANSPOSE(DESIGN) * RETVEC), J)".

Can anyone help explaining me what I am doing wrong?
Thank you!

Hie,
Is there a way to add random effect in a system?
When i go on new object/system a white window allows me to specify my system of equation but it seems not possible to specify that i want to add random effect to my equation.

VECM forecasting errors in Version 9.5

I am just wondering if the built-in forecasting function for VECM is wrong. I noticed that the forecasts produced from the forecast function or (button) will not produce the summary statistics for the individual equation. Can someone confirm that the function is correct? You can't produce the same statistics as the one reported in the vector error correction model.

Using a simple example below

wfopen "base.wf1"
genr logab=log(ab)
genr logrer=log(rer)
genr logus_inc=log(us_inc)
genr logwti_p=log(wti_p)

'VECM
smpl 1992M04 2008M12
var vecm1.ec(e,2) 1 2 logab logrer logus_inc logwti_p
smpl @all
vecm1.fit(e,g) _ef
smpl 1992m04 2008m12
genr diff=(d(logab)-d(logab_ef))^2
scalar SSR= @sum(diff)

SSR should produce the same in-sample sum of squared residuals of 0.395 as in the vecm1 output.

If I use the way we did it in the old version

vecm1.makemodel(mod1)
'smpl 1992m04 @last
smpl @all
mod1.solve(d=d)

The produced forecasts are very different from the summary stat provided. Can someone clarify this?

LENGHT SELECTION: Estimation sample VAR

Hi,
I am trying to estimate the optimal lag length in a VAR estimation. However, when I open the lag length window I don't understand how is expressed the estimation sample. I would like to input as estimation sample 1985q1 2016q1, the problem is that when I write those dates in the estimation sample box and press ok EViews tells me that this date expression is "illegal". And when I click on lag length this is what comes out in the estimation sample box ( please look at the attachment: 1 125

Could you please help me to figure it out what does it mean and how I have to write the estimation period?
Thank you.

Run a regression with multiples dummy variables

Hi,

I need to run a regression with multiple dummy variables as follows:
CAR    National    Top
6.24%    1     0
-2.96%    1     0
8.77%    1     0
-0.57%    0     0
-15.86%    1     0

Do I need to identify my variables as dummy (all columns are 1 and 0, the software should recognise)? I've got a "syntax error"

Many thanks in advance.

No, you don't need to tell EViews they are dummies.

You're probably doing something else wrong, but without knowing what you're doing, we can't say what you're doing wrong.
