建立了二进制数据的相似系数的一组直观明显的性质。从文献中可获得的系数的严格检查表明，他们都不满足所有这些属性，并提出了一个新的系数，以消除这种不便。新系数的分布研究了非常大的，完全随机样本的OTU的[操作分类单位]，并构建了一个表，以显示其临界值在不同的显着性水平。给出了一个数学附录来演示用于构造不同大小的完全随机样本的过程。
A set of intuitively obvious properties of a coefficient of similarity for binary data is established. Critical examination of the coefficients available from the literature shows that none of them satisfy all these properties, and a new coefficient is proposed to obviate this inconvenience. The distribution of the new coefficient is studied on very large, perfectly random samples of OTU''s [operational taxonomic units], and a table is constructed to show its critical values at different significance levels. A mathematical appendix is given to demonstrate the procedure used to construct perfectly random samples of different size.
