Multidimensional scaling

Multidimensional scaling (MDS) is a statistical technique often used in and data visualisation. It is a procedure for producing a lower-dimensional data suitable for graphing or 3D visualisation from a high-dimensional data set, whilst preserving some of the most prominent "distance" relationships of the high-dimensional data set.

Applications include scientific visualisation and data mining in fields such as cognitive science, psychophysics and psychometrics. The technique is also used in marketing.
