Redundant Variables Test
Posted: Mon Feb 20, 2012 6:39 am
Hi!
We got an assignment where we are suppose to make a multiple regression analysis. I estimated the regression with LS (4 independent variables) and then we are asked to perform a "redundant variables test". Now, I wonder: Since I can already see by the p-values in the estimation output which variables are significant, is there any meaning/advantage in doing a joint test like the redundant variables test? or is our professor just trying to teach us HOW to make one. So that we will remember to make one when we get to e.g. panel data or times series assignments?
