Kruskal–Shepard scaling

a type of multidimensional scaling applied to judgments of similarity or dissimilarity for pairs of items (e.g., cities). The dissimilarities are represented by distances between items in a highly dimensional space: Larger distances indicate greater dissimilarity. [William Henry Kruskal (1919–2005), U.S. statistician; Roger N. Shepard (1929– ), U.S. experimental and cognitive psychologist]
