一种衡量排序一致性的新指标AI 解读

A measure of the agreement between the rankings of N objects by k observers is proposed which indicates the extent to which the objects may be divided into groups of objects such that each object in a group is preferred by all k observers to each object in subsequent groups. Some results are obtained on the distribution of the statistic under the null hypothesis of random permutations of the first N integers, and a simulation study is described which investigated the power…

两组排序的一致性度量AI 解读

A measure of the agreement between two rankings of a set of objects is proposed. This measure not only gives an indication of the overall correspondence of the rankings, but also specifies the objects in each sequence which are contributing to the agreement. The null distribution of the measure is found to be related to a standard problem in combinatorics: given a random permutation of the first N integers, what is the distribution of the length of a longest monotone…
