How to reduce multicollinearity in multiple regression?

Answer 1

hlo dear
Remove highly correlated predictors from the model. If you have two or more factors with a high VIF, remove one from the model. ...Use Partial Least Squares Regression (PLS) or Principal Components Analysis, regression methods that cut the number of predictors to a smaller set of uncorrelated components.
