detecting multicollinearity

Postby mscarlatos » Tue Jun 29, 2010 7:46 am

I am unable to pull up Eviews Help anymore for some reason. Could someone tell me whether or not Eviews can run a collinearity test between two or more variables?

From an estimated equation there are a few diagnostics to help you determine collinearity between the regressors - Variance Inflation Factors, and Variance Decomposition.

Dear Mr Evans: Thank you but could you be a bit more forthcoming: I run a regression but where do I look for VIF and Variance Decomposition? I ask since I cannot find them under any of the Views or Procs. Thank you.

Under view, I see "coefficient tests" under which I do not see anythign measnuring multicollinearity unless "redundant variables" measures that. However, without even regressing, I find under "quick"..."group statistics"..."correlations." Does the latter serve as a measure of collinearity?

What version of EViews are you using?

The multicollinearity diagnostics were introduced in EViews 7.

Just out of curiousity, why are you concerned about multicollinearity?
