      Question

      Which of the following test is used for

      Multicollinearity?
      A Part Test Correct Answer Incorrect Answer
      B Glejser Test Correct Answer Incorrect Answer
      C VIF Correct Answer Incorrect Answer
      D Breush-Pagan Test Correct Answer Incorrect Answer

      Solution

      VIF quantifies the severity of multicollinearity in an ordinary least squares regression analysis. It provides an index that measures how much the variance (the square of the estimate's standard deviation) of an estimated regression coefficient is increased because of collinearity (See test 1 for numerical example)
