Hi there,
I have estimated a state-space model for the period 1981Q1 to 2007Q4.
Now, I would like to use the estimates to forecast until 2010Q2 (the signal variables are available only until 2007Q4). I read in some textbooks that the Kalman filter can estimate “missing values” (which in my case would be from 2008Q1 to 2010Q2). Does Eviews 7 perform such forecasts?
Thanks very much for your help.

Use the forecast proc.

Re: kalman filter and forecasting "missing values"
I did use Proc Forecast but I am getting "NA" for the period 2008q1-2010Q2. Could you please tell me what are the steps to follow? I've tried a few things already but I am getting no results.
Thanks for your reply.

Hi Glen,
Could you please help me with the forecast?
I am still getting NA with proc forecast.
Do I have to change the sample and range period in the workfile? Itried that and I re-estimated the model but I still got nothing.
Thanks,
Mara

Re: kalman filter and forecasting "missing values"
That's a hard question to answer without seeing your model. A likely possibility is that you have non-state variables in your signal equation which do not have values for the out-of-sample period.

Yes, I do have 4 pre-determined variables in the state specification.
I assume I need to supply values for those variables for the period I want to forecast (UPS!). I'll do that now and see what happens.
Thanks very much for your reply.
