Problems to run combination test

Postby sunnyeviews » Tue Dec 15, 2015 1:11 pm

Dear Sir or Madam,

I have just succesfully completed forecast comparison and evaluation. I have only one problem. I did not get any results from combination test. "F-stat" and "F-prob" columns show only "NA" everywhere. I wonder what could be the reason for that?

Additionally under the title "Evaluation statistics" I received a text saying: "*Trimmed mean could not be calculated due to insufficient data". I wonder what could be the reason for that? I have all the data (10 different forecast 2004-2014).

Best regards,

EViews Gareth

Hard to say without seeing the workfile and knowing exactly what you did.
