I am posted with this question that I really need help!
A regression model includes 10 explanatory variables; the value of R squared for explanatory variable X1 with respect to other 9 variables is 0.67
I tried to use the formula as follows but the answer is wrong... Can anyone here help me with getting the right ans? Thanks in advance!
VIF = 1/(1-R^2) = 1/(1-0.67) = 3.03
FYI. 3.03 is a wrong answer
