Could you please enlighten me? Have you used the excel file?
I inserted to the existing file the forecast lrconsf from the excel (f row) . (as you will see in the new workfile I attached)
When I run the ridge trace what do I put in dependant: the forecast? lrconsf? I tried everything and I am just getting a blank graph?
I am new to Eviews, sorry for the 'stupid' questions!
Thanx in advance!

As I said earlier the ridge regressions gives me the results, but the ridge trace add-in is giving me the blank graph
I made you a print screen and I think you will understand the problem.

You appear to be entering only a single biasing constant for the Trace. As the instructions indicate, you need to enter a list of values.

Thank you, that was clearly my bad!
But again one problem, hopefully the last!
Given the automated sort of values in the ridge trace (0 , 0.5..etc) I run it and I got the following error message!

Unbelievable or what? We are doing the exact same thing and getting 2 different results. Perhaps I miss a plugin or something? I installed the plugin straight from the site, no problem in installation...
Do not know that to say...

Added to my previous question about the ridge regression , I would like to ask you what exactly does the VIF represent in the ridge trace
Thanx again.
