 

Spearman Distance Spearman distance is a square of Euclidean distance between two rank vectors. Formula Example: We have ask two persons, A and B about their preference on public transport and here is their ordering vector A = [Bus, Van, Train] and B =[Van, Bus, Train] Suppose we set [Bus, Van, Train] as patternvector we get rank vector A=[1, 2, 3] and B = [2, 1, 3]. Thus, we can represent the two vectors as two points in threedimensional space. Point A has coordinate (1, 2, 3) and point B has coordinate (2, 1, 3).
The Spearman distance of preference between A and B is Preferable reference for this tutorial is Teknomo, Kardi. Similarity Measurement. http:\\people.revoledu.com\kardi\ tutorial\Similarity\
