question 22

Multiple Choice

Which of the following statements are true?

• A) The idea behind the stepwise procedure is that with forward selection, a single variable may be more strongly related to y than either of two or more other variables individually, but the combination of those variables may make the single variable subsequently redundant.
• B) When the predictors \(x _ { 1 } , x _ { 2 } , \ldots , \ldots , x _ { k }\)
• Are highly interdependent, the data is said to exhibit multicollinearity.
• C) There is unfortunately no consensus among statisticians as to what remedies are appropriate when sever multicollinearity is present. One possibility involves continuing to use a model that includes all the predictors but estimating parameters by using something other than least squares.
• D) All of the above statements are true.
• E) None of the above statements are true.
