Near singular matrix

Postby windyboo » Wed Sep 17, 2014 12:29 pm

Hi,

I've tried to regress panel data.

First, I've followed the instructions (http://forums.eviews.com/viewtopic.php?t=74&f=7) to enter data panel into a panel workfile (EViews 6). Second, I've coded as suggested by EViews Gareth in my last post (http://forums.eviews.com/viewtopic.php?f=4&t=10907).

So, I've used this code:

gdp unemployment(-1) inflation(-1)

It said: Error Message - Near Singular Matrix.

What did I do wrong?

(Thank you so much in advance.)

Your regressors are probably perfectly colinear.

Check your data. Make sure you don't have errors in it.

Yesterday, maybe I was doing something differently because today the message error says:

''Near singular matrix in computation of Swamy-Arora RE component variances for estimate of RE innovation variance''

What does that mean?
