Re: Rolling GARCH with forecasting

So should I assume that the problem would be with this specific version?

Re: Rolling GARCH with forecasting

Hi again,

The build version the university uses is January 7 2010.

I also tried the same with Eviews 5 and I did not have any problems. So probably there is something with this version. I do not know if you have any other suggestion.

Re: Rolling GARCH with forecasting

Dear Gareth, I have an updated copy of eviews 7. I am interested in forecasting with GARCH the conditional volatility of my series (sample in the Eviews file attached).I estimated GARCH with the first 1800 observations of my dataset. I click forecast, sample c for the mean equation, click static and...

Re: Rolling GARCH with forecasting

Ok I will try to be as self-explanatory as I can. I built a GARCH (1,1) model for the series 'sample' as you can see from the specification of the equation in the file. So I put in the mean equation ' sample c' and then in GARCH 1 and ARCH 1 and threshold 0. I used the first 1800 observations for th...

Re: Rolling GARCH with forecasting

I am sorry I did not send you the eviews file with the equation.

Now you will be able to see it.

Re: Rolling GARCH with forecasting

Hi, Probably its a stupid question but I am forecasting the conditional volatility with GARCH(1,1) model using static forecast in eviews. When I click forecast my last observation in the out-sample-forecast is N.A for both the conditional volatilty and the s.e (see vol1, vol2 in the attached). Isn't...

Re: Diebold_Mariano Test

Dear Gareth, the problem is that I do not get the workfile either...
any ideas why? this is my data

when I press run and I get a new box 'run program' I should just press 'ok' right?

Sorry if the questions are stupid, I am quite a rookie...

Re: Diebold_Mariano Test

Thanx Gareth,

I 've done what you said, I pressed run without having any errors but I do not get any results...

Do I have to do something else to see the results?

Re: URGENT: AIC and SBIC criterion for forecasts

Well it isn't clear what you mean by "AIC of forecast". The AIC is a statistic based upon a likelihood function. I don't see how that fits in with a forecast. To make it more clear I have two series f1, f2 and I want to calculate their AIC1,AIC2 and BIC1,BIC2! This is what I want. I am a ...

Re: URGENT: AIC and SBIC criterion for forecasts

The point is to estimate the quality forecast by the bic and sic, I was just not sure if to get the bics and sics have to do a simple regression with each one or with all the forecasts together like: dependant sample and independent f1 f2 f3 ; it is just when I use one forecast the bics and sics of ...

URGENT: AIC and SBIC criterion for forecasts

Hello, I would like to now if it is possible to estimate the bic and aic criterion for some forecasts. For example if I have the 3 forecast results f1,f2,f3 and the original series 'sample' if i perform a regression for each one, meaning for example dependant variable sample and independent f1, I wi...
