| Abstract: | A nonparametric selection procedure ??bs was proposed by Bechhofer and Sobel (1958) and studied by Dudewicz (1971) in comparison with other procedures under normal and uniform alternatives. He found ??BS always required larger sample sizes, sometimes substantially so. For 2-point populations we find more extreme results. We also find that ??BS may be substantially better than reasonable competitors designed specifically for 2-point populations. Finally, a new nonparametric selection procedure (conjectured to be better than ??BS) is proposed. |
