We can then repeat this process for the other two variables assists and rebounds. It turns out that the VIF for the three explanatory variables are as follows: points: 1.76. assists: 1.96. WebThere are multiple ways to overcome the problem of multicollinearity. You may use ridge regression or principal component regression or partial least squares regression. The alternate way could be to drop off variables which are resulting in multicollinearity. You may drop of variables which have VIF more than 10.
