INDIVIDUAL DIFFERENCES IN MULTIDIMENSIONAL SCALING*

A Bayesian approach to modeling group and individual differences in multidimensional scaling

Multidimensional scaling (MDS) models of mental representation assume stimuli are represented by points in a low-dimensional space, such thatmore similar stimuli are represented by points closer to each other.We consider possible individual differences inMDS representations, using the recently proposed KINDSCALmodel,which allows for both sub-groups of peoplewith different representations, and i...

What Weight Should Weights Have in Individual Differences Scaling?

Recently, individual difference scaling has become one of the most active fields of research in psychometrics. Numerous models and algorithms have been proposed but relatively little evidence as to the validity of the produced representations is available so far. To shed some new light on this issue we will reanalyze some data collected by Green and Rao (1972) via PINDIS (Procrustrean INdividua...

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...
