Forecasting with Models
Posted: Wed Apr 21, 2010 9:38 pm
I am experiencing a great deal of difficulty with an AR(1) forecast assignment that is due for class tommorow and, I would GREATLY appreciate your help if you are able to give it.
My Workfile Range and Sample are 1994m11 - 2011m02.
My observations span 1994m11-2010m02. I need to forecast 2010m03 - 2011m02.
I need to create and out-of-sample forecast from and estimation with multiple independent variables regressed on a dependent variable. When I create the estimation, I specify the sample range as 1994m11-2010m02. In the attached workfile, projectfinal_eq01 is my specifed equation. When I hit forecast, i alter my sample to 2010m03 - 2011m02 and recieve an error "unable to compute due to missing data."
Following this same process for a univariate estimation, I can get the forecast without issue. This can be seen in revolncbunivariatef if you look at the attached workfile.
What am I doing wrong?
I attached the workfile so you can see this for yourself. I am pretty desperate to get this all worked out!
