question 92

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.
