Using Multidimensional Scaling for Assessment Economic Development of Regions
Addressing socio-economic development issues are strategic and most important for any country. Multidimensional statistical analysis methods, including comprehensive index assessment, have been successfully used to address this challenge, but they donchr('39')t cover all aspects of development, leaving some gap in the development of multidimensional metrics. The purpose of the study is to const...
متن کاملRescaling Non-metric Data to Metric Data Using Multi-Dimensional Scaling
Rescaling of nominaland ordinal-scaled data to interval-scaled data is an important preparatory step prior to applying parametric statistical tests. Without rescaling, the analyst typically must resort to non-parametric tests that are less robust statistically than the metric counterparts. Multi-dimensional scaling (MDS) is a procedure that can be used to perform the desired rescaling. This pap...
متن کاملData Error Reduction in Nonmetric Multidimensional Scaling
The aim of Multidimensional Scaling (MDS) is to search for a geometrical pattern of n points, on the basis of experimental dissimilarities data between these points. For nonmetric MDS, one may use ordinal data as dissimilarities. In general, as these dissimilarities are empirical, they may be errorful. Thus, in order to obtain better scaling solutions, it is of great interest to reduce error in...
متن کاملDimensionality Reduction via Euclidean Distance Embeddings
This report provides a mathematically thorough review and investigation of Metric Multidimensional scaling (MDS) through the analysis of Euclidean distances in input and output spaces. By combining a geometric approach with modern linear algebra and multivariate analysis, Metric MDS is viewed as a Euclidean distance embedding transformation that converts between coordinate and coordinate-free r...
متن کاملArtefactual Structure from Least-Squares Multidimensional Scaling
We consider the problem of illusory or artefactual structure from the visualisation of high-dimensional structureless data. In particular we examine the role of the distance metric in the use of topographic mappings based on the statistical field of multidimensional scaling. We show that the use of a squared Euclidean metric (i.e. the SSTRESS measure) gives rise to an annular structure when the...
