Multidimensional scaling (MDS) is a versatile technique for understanding and displaying the structure of multivariate data. This technique has seen wide application in the behavioral sciences and has led to increased understanding of complex psychological phenomena. MDS has been used to assess cognitive...
R provides functions for both classical and nonmetric multidimensional scaling. Assume that we have N objects measured on p numeric variables. We want to represent the distances among the objects in a parsimonious (and visual) way (i.e., a lower k-dimensional space). ...

Multidimensional scaling is the problem of representing n objects geometrically by n points, so that the interpoint distances correspond in some sense to... J Kruskal - 《Psychometrika》 被引量: 1.0万发表: 1964年 Nonmetric multidimensional scaling: A numerical method No abstract is available for ...
Non-metric multidimensional scaling, or NMDS, is known to be an indirect gradient analysis which creates an ordination based on a dissimilarity or distance matrix. It attempts to represent the pairwise dissimilarity between objects in a low-dimensional space, ...
Multidimensional scaling (MDS) is a two-way technique (individuals and variables) of multivariate data analysis. It provides a visual representation of the pattern of proximities (similarities or distances) among a set of objects, using a factorial approach, to simplify and reduce datasets. With th...
Multidimensional scaling (MDS) is a means of visualizing the level of similarity of individual cases (think e.g. sites) of a multivariate dataset. It refers to a set of related ordination techniques used in information visualization, in particular to display the information contained in a distance...
This paper investigates the use of multidimensional scaling in the evaluation of fractional system. Several algorithms are analysed based on the time response of the closed loop system under the action of a reference step input signal. Two alternative performance indices, based on the time and frequ...
