Replicated Paired Comparisons between Two Objects: The (k,r)-Series
两个对象的重复配对比较：（k,r）序列
The problem considered here is selecting the better of two objects based on a series of replicated paired comparisons between the objects. A (k, r)-series, a generalization of the ordinary k-series, is defined as a sequential selection procedure such that the object selected is the first one to win k comparisons, provided it is ahead by at least r comparisons. The relationship of a (k, r)-series to Wald's sequential probability ratio test (SPRT) is discussed and this…
