Which of the Following Is the Difference Between Forward Selection

question 40

Multiple Choice

Which of the following is the difference between forward selection and standard stepwise regression?

• A) In the standard stepwise regression, variables that were added at earlier steps can be removed at later steps, which is not the case with forward selection.
• B) The standard stepwise approach will generally produce a regression model with a higher R-square value than the forward selection approach.
• C) Forward selection begins by selecting the variable with the highest correlation with the dependent variable and then proceeds to select subsequent variables in order of their F-to-enter value, while
• Standard stepwise selects the variables in the order specified by the decision maker and then removes
• Them from the model as needed.
• D) There are no appreciable differences between the two methods, just different names for the same technique.
