Quizplus · Accepted Answer

Best-subsets regression is considered non-heuristic because it systematically evaluates all possible subsets of predictors, rather than relying on a specific algorithm or set of rules for selection. Forward selection, backward elimination, and stepwise regression are all heuristic procedures that make assumptions about the relationships between predictors and use certain criteria to add or remove variables.
