我们讨论了相似性和相异度系数的定义和性质，包括它们的度量和欧几里德状态。在众多可用的系数中，我们详细介绍了一些更常用的二元和定量变量。首先，我们讨论了一对单位之间的相似性评估措施，表明一些系数是单调的功能，彼此和许多系数是特定的情况下，整体措施的相似性。最后，我们可以用来评估种群间的相似性的措施。
We discuss definitions and properties of similarity and dissimilarity coefficients, including their metric and Euclidean status. Among the plethora of available coefficients, we give details of some of the more commonly used with binary and quantitative variables. First, we discuss measures for evaluating similarity between a pair of units, showing that some coefficients are monotonic functions of each other and that many coefficients are particular instances of an overall measure of similarity. We end with measures that can be used to assess interpopulation similarity.
