Unidimensional Vertical Scaling in Multidimensional Space

Unidimensional scaling of multidimensional facial expressions.

It is often possible to construct unidimensional scales of multidimensional stimuli. Thurstonian scaling theory predicts that the standard deviations of differences in unidimensional paired-comparisons scaling of such stimuli should covary with the qualitative similarity between the stimuli being compared. In a test of this prediction, 78 5s judged 11 facial expressions from the Lightfoot serie...

Unidimensional Scaling

Self - Concept : Multidimensional or multifaceted , unidimensional ?

unidimensionality of a multi-faceted, hierarchical model of self-concept using the Extended Logistic Model of Rascb. The multi-faceted hierarchical model contained three 1s t order facets, each composed of three 2 nd order facets. Academic self-concept consists of Capability, Perceptions of Achievement and Confidence in academic life: Social self-concept consists of Same-sex peer, Opposite-sex ...

On Dimensionality of Embedding Space in Multidimensional Scaling

Abstract. Multidimensional scaling is a technique for exploratory analysis of multidimensional data widely usable in different applications. By means of this technique the image points in a lowdimensional embedding space can be found whose inter-point distances fit the given dissimilarities between the considered objects. In this paper dependence of relative visualization error on the dimension...

Linkage Disequilibrium Map by Unidimensional Nonnegative Scaling

A unidimensional nonnegative scaling model is used to construct linkage disequilibrium (LD) maps for human genome. The proposed constrained scaling model can be solved efficiently by transforming it to an unconstrained model. A LD map based on Hapmap data of 50000 SNPs is constructed by the proposed method using PC Clusters.
