In this paper we propose a distribution-free treatments versus control multiple comparisons procedure, based on the control sample median, that is appropriate when the control sample observations are easy and relatively inexpensive to collect, while the treatments data are costly and/or difficult to obtain. For this procedure the control sample has a fixed sample size and the treatments have random sample sizes determined by a truncated inverse binomial sequential sampling…

部分序贯检验中指示集选择的最优性准则AI 解读

Wolfe (1977a) introduced the concept of a partially sequential two-sample hypothesis test and studied some of the properties for a general class of such procedures. In this paper we deal with criteria for selecting an indicator set for use in a partially sequential test. In particular, we show how the Neyman-Pearson lemma can be used to generate an asymptotically optimal indicator set, in the sense that it corresponds to an asymptotically most powerful partially sequential…
