Multidimensional scaling (MDS) aims at representing high-dimensional data in a low-dimensional space so that data can be visualized, analyzed, and interpreted in the low-dimensional space to uncover useful data patterns. This chapter describes MDS, software packages supporting MDS, and some applications of MDS with references.
We are given n data items in the p-dimensional space, xi = (xi1, …, xip), i = 1, …, n, along with the dissimilarity δij of each pair of n data items, xi and xj, and the rank order of these dissimilarities from the least similar pair to the most similar pair:
(15.1) |
where M denotes the total number of different data pairs, and M = n(n
