Dear all,
I'm on Eviews 5 and i have a problem with forecasting. I want to see the Mean Root Squared Error for two series, namely
a) Overnight Interest rates
b) Taylorrule with prespecified coëfficients.
I did some googling and it seems as if everytime you want to do a forecast, Eviews wants to estimate the coefficients first. I already know the coefficients i want to use, and hence, want to skip this feature. So basically: i want to do a forecast without regressing first. Can anyone help me with this?
Thanks in advance,
Kind regards,
Thomas Kooiman.

Re: Forecasting a series without regressing
Thank you kindly for your response. If i understand what you're saying i need to construct a serperate series that contains all the coefficients and variables that are in the Taylor rule. After that I do a regression with command
ls overnight_int overnight_int_taylor
and proceed with a forecast..
ls overnight_int overnight_int_taylor
and proceed with a forecast..

No, I'm just saying you construct the forecast directly by hand.

Re: Forecasting a series without regressing
Could you please clarify how exactly this is done? I appreciate your answers thusfar, but they haven't enabled me to figure out how to do this.
The following screenshot depicts the two series for which i want to know the root mean squared error.
Could you tell me the specific code on how to do this in this instance? If I know that i can continue to do it for the rest of my dataset.
Thanks a bunch in advance!

I'm confused. What are you trying to do? Where do those two series fit into the forecast you're trying to do?

Re: Forecasting a series without regressing
Yes, I think i've been unclear. My apologies.
I think my use of 'forecasting' wasn't right, i don't think i want to forecast anything.
All i want to do is the following: calculate the RMSE for the two series depicted in the graph. So: for overnight_int and overnight_int_taylor, for the entire period (1991Q11998Q4). That's it. Hope this clears up what i'm asking.

 Nonnormality and collinearity are NOT problems!

Re: Forecasting a series without regressing
Subtract one from the other and look at the standard deviation?
