COMPUTABLE GENERAL EQUILIBRIUM

Postby piorember1990 » Sun Jul 26, 2015 11:56 am

Please I am learning how to perform Computable General Equilibrium using Eviews7 but I'm finding it difficult in going beyond the stage with the following codes:
CALIBER.SOLVE(s=d, d=s, o=n)
DMR.SOLVEOPT(s=d, d=s,c=1e-15, o=n)
DMR.SCENARIO(c) BASELINE
SOLVE DMR
Whenever I try running it, Eviews7 reports error message: Unable to compute due to missing data in "RHO=(1/sigma)-1" in "DO_ CALIBER.SOLVE(S=D, D=S, O=N)"

Please I need help

We'll need a lot more information, including, preferably, the workfile and whole program.

That seems to run just fine in my EViews 7 (and 8, and 9).

Is your copy of EViews 7 fully up to date?

Good day sir, I am having a challenge of evaluating forecast. I did a forecast using eviews 9 but can't evaluate the forecasts. Each attempt gives me all zeros for RMSE, MAPE, Theil and all other statistics.
Please I need some help.

Can you provide your data and instructions on exactly what you did?

Thanks for your prompt response Gareth.
I intend to make a monthly forecast of CPI from January 2016 to December 2016 and evaluate the forecasts. I have data from January 1995 up to December 2010 (Training set or estimation sample).
I was able to implement the forecast but unable to evaluate the forecast performance. I would open the forecast series and click on view then select forecast evaluation but RSME, MAPE, MAE and Theil statistics all appear with zero values.
Thank you.

Not sure I understand - you need to have one series of actual values and then one or more series of forecasts

Thanks Gareth, but sorry I could not attached the series as they appeared in my eviews workfile. However, I have copied the estimation or training sample series and the forecasted series cpi and cpi_f in this workfile respectively.
My major problem is that, I can not evaluate the forecasts.
Thanks.
