چکیده
The smacof package offers a comprehensive implementation of multidimensional scaling (MDS) techniques in R. Since its first publication (De Leeuw and Mair 2009b) the functionality has been enhanced, several additional methods, features utilities were added. Major updates include complete re-implementation unfolding allowing for monotone dissimilarity transformations, including row-conditional, circular, external unfolding. Additionally, constrained MDS was extended terms optimal variables. Further additions various tools functions goodness-of-fit assessment, unidimensional scaling, gravity MDS, asymmetric Procrustes, biplots. All these new functionalities are illustrated using variety real-life applications.

Multidimensional Scaling and Unfolding
Multidimensional scaling (MDS) techniques are statistical techqnies that convert information about distances between a number of objects into a spatial representation of these objects. These techniques were first discussed systematically in psychometrics [Torgerson, 1958; Coombs, 1964] as multidimensional extensions of univariate psychophysics and sensory scaling. Because they needed considerab...
متن کاملMultidimensional Unfolding by Nonmetric Multidimensional Scaling of Spearman Distances in the Extended Permutation Polytope.
A multidimensional unfolding technique that is not prone to degenerate solutions and is based on multidimensional scaling of a complete data matrix is proposed: distance information about the unfolding data and about the distances both among judges and among objects is included in the complete matrix. The latter information is derived from the permutation polytope supplemented with the objects,...
متن کاملApplications of Multidimensional Scaling to Molecular Conformation 1 2 Multidimensional Scaling
Multidimensional scaling (MDS) is a collection of data analytic techniques for constructing conngurations of points from information about interpoint distances. Such constructions arise in computational chemistry when one endeavors to infer the conformation (3-dimensional structure) of a molecule from information about its interatomic distances. For a number of reasons, this application of MDS ...

متن کاملUsing 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...
