一般方法的困难进行了讨论，特别是;需要讨论的相似性只与特定的尺寸，损失的信息时，配置减少到指数，需要解释的相似性指数作为一个相对的，而不是作为一个绝对的措施，和一般的非可比性的规模单位参与配置文件。给出了测度D。对于两个轮廓，这是相应分数的平方偏差之和，并且是相异性（k变量超空间中的距离）的一般表达式。27篇参考文献。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
General methodological difficulties are discussed, particularly; the need to discuss similarity only with respect to specified dimensions, loss of information involved when configurations are reduced to indices, the need to interpret a similarity index as a relative rather than as an absolute measure, and the general non-comparability of scale units involved in profiles. The measure D is presented. This is, for two profiles, the sum of the squared deviations of corresponding scores, and is a general expression for dissimilarity (distance in the hyperspace of k variates). 27 references.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
