A Minimax Procedure for Choosing between Two Populations Using Sequential Sampling
利用序贯抽样在两个总体间选择的极小极大程序
Summary When a choice has to be made in favour of one of two populations the cost of sampling (experimenting) in order to obtain information on which to base the decision must be balanced against the cost of making the wrong choice. Wald’s (1950) minimax procedure is used to determine a sequential method of sampling when a decision is to be made between two normal populations on the basis of their sample means. It is assumed that the cost of making a wrong choice is given by…
