It is known that the so-called paternity index is also a likelihood ratio statistic for testing that an alleged father is the true father. Unfortunately the likelihood ratio test can sometimes lead to unsatisfactory results because of its dependence on the phenotype combinations of the mother and child. A new, conditional likelihood ratio test, which we call the ancillary test, is proposed in which statistical testing is carried out conditionally on the phenotypes of the mother and alleged father. An exact procedure is available which can be executed with reasonable facility on a microcomputer.
众所周知，所谓的父权指数也是用于检验被指控父亲是否为真正父亲的似然比统计量。不幸的是，似然比检验有时会因依赖母亲和孩子的表型组合而导致不尽人意的结果。本文提出了一种新的条件似然比检验，我们称之为辅助检验，该检验是在母亲和被指控父亲的表型条件下进行统计检验的。有一个精确的程序可供使用，它可以在微型计算机上相当方便地执行。
