Hi,
How can I eliminate the autocorrelation to reach Durbin Watson close to 2?
What are the steps to do that?
Thank you in advance.

Look at the AR(1) command in the help system.

Hi,
I followed the instructions but a message appeared:” Insufficient number of observations”
Attached the snap shots of what I did.
Please help.
Thank you

Hard to say without seeing the workfile. I do note that you appear to have a three-dimensional panel with 2 observations per block. This may or may not be what you want...

This is the work file.
Are the results change if I use/not use the 3D panel data?
Thank you in advance.

EViews seems to think the time dimension is your 3rd dimension. You need it to understand that year is the time dimension.

It worked after I deleted the time dimension.
Thank you indeed for your help.
