提出了一种新的相似性度量方法--“稀释因子扩散”，或由此衍生出的“拟合度”参数。这具有的优点是，可以使用未经任何变换的原始数据，可以识别稀释的样品，并且可以容易地包括单个浓度值的误差。展示了在多变量聚类分析中使用该相似系数来构建树状图，并与属性空间中众所周知的欧几里得距离的相似度量和cosθ度量的使用进行了比较。
A new similarity measure is proposed, the ‘dilution factor spread’ or, derived from it, a ‘goodness of fit’ parameter. This has the advantage that raw data without any transformation can be used, diluted samples are recognized and errors of individual concentration values can easily be included. The use of this similarity coefficient in multivariate cluster analyses to construct dendrograms is shown and compared with the use of the well‐known similarity measure of Euclidian distance in attribute space and of the cosθmeasure.
