Question

Which of the following statements about the backward elimination procedure is false? a. It does not permit an independent variable to be reentered once it has been removed. b. It is a one-variable-at-a-time procedure. c. It does not guarantee that the best regression model will be found. d. It begins with the regression model found using the forward selection procedure.

Answer 1

c. It does not guarantee that the best regression model will be found.

Explanation:

Answer 2

c. It does not guarantee that the best regression model will be found.

Explanation:

Backward elimination (or deletion) procedure requires a subsequent removal of individual independent variables in an equation to derive an appropriate regression equation. It is a step-wise operation which make use of a predefined criterion for essential variables.

One of its main importance is that it ensure that the best regression model is found by removal of inconsequential variables.

Therefore, the appropriate answer to the given question is option C.
