Abstract
One approach to the problem of selecting predictor variables in the tw o-group classification situation is to compare the cross-validated cla ssification accuracies of all possible subsets. Because of the obvious time constraints of this approach for even a moderate number of predi ctors, a computer program was written to accomplish the task. The prog ram examines the cross-validated classification hit rates of all possi ble subsets of predictor variables and identifies the user-specified n umber of best subsets overall and for each subset size.
