The best-subsets regression method ________.
A)evaluates best subsets of models for a fixed number of dependent variables
B)adds one variable at a time to the multiple regression model and tests for significance
C)evaluates all possible regression models for a set of independent variables
D)removes one variable at a time from the regression model

Question

Quizplus · Accepted Answer

The best-subsets regression method evaluates all possible regression models for a set of independent variables, and selects the best model based on a chosen criteria (such as highest adjusted R-squared or lowest Akaike Information Criterion). It does not involve adding or removing variables one at a time, or evaluating fixed numbers of dependent variables.
