	Multidimensional scaling - Wikipedia, the free encyclopedia
		Multidimensional scaling (MDS) are a set of related statistical techniques often used in data visualisation for exploring similarities or dissimilarities in a given data set.
		Metric multidimensional scaling --- A superset of classical MDS, metric MDS assumes that there is a known parametric relationship between the elements of the item-item dissimilarity matrix and the Euclidean distance between the items.
		Non-metric multidimensional scaling --- In contrast to metric MDS, non-metric MDS both finds a non-parametric monotonic relationship between the dissimilarities in the item-item matrix and the Euclidean distance between items, and the location of each item in the low-dimensional space.

		A short elementary overview is presented on the use of multidimensional scaling as a method of data analysis, and as a tool for perceptual and cognitive modelling in psychology.
		Multidimensional scaling can be characterised by the generality of the type of observed relations which can be submitted to the data analysis on the one hand, and by the specificity of the type of geometrical representation of these relations on the other hand.
		Multidimensional scaling is particularly suited for the analysis of ordinal data, these are the non-metric scaling models.

		Nonmetric multidimensional scaling is a technique that takes any similarity (e.g., proximity) matrix and represents it in any number of dimensions as distances between the original items in the matrix.
		Multidimensional scaling is a multivariate analysis that accomplishes this task.
		In a traditional multidimensional scaling analysis, the analyst specifies the number of dimensions into which the set of points will be fit.

	Multidimensional Scaling (MDSCAL)
		The uses of non-metric multidimensional scaling are similar to those of factor analysis, e.g.
		In practice, the scaling computation stops, in any given number of dimensions, because the stress reaches a sufficiently small value (STRMIN), the scale factor (magnitude) of the gradient reaches a sufficiently small value (SRGFMN), the stress has been improving too slowly (SRATIO), or the preset maximum number of iterations is reached (ITERATIONS).
		Because non-metric scaling uses only ordinal properties of the data, nothing need be assumed about the quantitative or numerical properties of the data.

	Multidimensional scaling in marketing - Wikipedia, the free encyclopedia
		In marketing, Multidimensional scaling (MDS) is a statistical technique for taking the preferences and perceptions of respondents and representing them on a visual grid.
		These grids, called perceptual maps are usually two-dimensional, but they can represent more than two.
		For each product pair they are asked to rate similarity (usually on a 7 point Likert scale from very similar to very dissimilar).

	Multidimensional scaling: (Site not responding. Last check: 2007-10-22)
		Multidimensional scaling (MDSCAL) is a multivariate statistical technique, which through computer applications seeks to simplify complex information.
		One interesting feature of the method is that it does not need fully quantitative measures of similarity and difference: it is sufficient to know, for each unit, which the nearest unit is, and then the next and so on in rank order.
		On use of the technique was the application employed in the reconstruction of the geography of the Mycenaean kingdom of Pylos in Greece (c.1200 B.C.)carried out by English archaeologist John Cherry.

	Multidimensional Scaling
		From a non-technical point of view, the purpose of multidimensional scaling (MDS) is to provide a visual representation of the pattern of proximities (i.e., similarities or distances) among a set of objects.
		In other words, the raw input data is compared directly to the map distances (at least in the case of dissimilarities: see the section of metric scaling for information on similarities).

	Multidimensional Scaling
		Multidimensional scaling (MDS) can be considered to be an alternative to factor analysis (see Factor Analysis).
		In general, the goal of the analysis is to detect meaningful underlying dimensions that allow the researcher to explain observed similarities or dissimilarities (distances) between the investigated objects.
		In summary, MDS methods are applicable to a wide variety of research designs because distance measures can be obtained in any number of ways (for different examples, refer to the references provided at the beginning of this section).

		He regularly teaches courses on multidimensional scaling (MDS) at the Essex Summer School in Social Science Data Analysis, at the ICPSR Summer Program in Quantitative Methods, the Master's course in Quantitative Analysis at the Katholieke Universiteit van Brussel.
		MDS is thus akin to factor analysis, clustering and correspondence analysis and the course will show how these methods are inter-related and how MDS models can provide a framework for analysis of data as different as correlations, tables, categories, measures of association, multiple time and multi-mode data.

		This pattern of connectivity is difficult to explain on the basis of Euclidian spaces.
		Traditional multidimensional scaling techniques place stimuli as points in a multidimensional space with similarity inversely related to the distances between points.
		Typically, pairwise similarity judgments are used to infer these multidimensional representations but I have shown how to extend this framework to learn semantic spaces for words based on word association (Steyvers, Shiffrin, and Nelson, 2004) and perceptual representations for faces based on physical features as well as similarity ratings (Steyvers and Busey, 2000).
