A Geometrical Analysis Of The Unfolding Model: General Solutions
Peer reviewed Peer reviewed
Davidson, John – Psychometrika, 1973
The present paper generalizes the results obtained by Davidson (1972) for nondegenerate stimulus configurations. (Author)
Descriptors: Geometric Concepts, Models, Multidimensional Scaling, Psychometrics
Nonlinear Submodels Of Orthogonal Linear Models
Peer reviewed Peer reviewed
Bechtel, Gordon G. – Psychometrika, 1973
It is the purpose of this paper to suggest the orthogonal analysis of variance as a device for simplifying either the analytic or iterative problem of finding LS (least squares) estimates for the parameters of particular nonlinear models. (Author/RK)

Linear Programming Techniques For Multidimensional Analysis Of Preferences
Peer reviewed Peer reviewed
Srinivasan, V.; Shocker, Allan D. – Psychometrika, 1973
This paper offers a new methodology for analyzing individual differences in preference judgments with regard to a set of stimuli. (Author)

Matrix Models and the Search for Structure in Subject-Majors Circulation: A Methodological Study.
Peer reviewed Peer reviewed
McGrath, William E.; And Others – Library and Information Science Research, 1988
Four models for conceptualizing a circulation matrix containing the number of books borrowed according to subject and majors of student borrowers compare (1) majors; (2) subjects; (3) disciplines, suppressing the distinction between majors and subjects; and (4) majors with subjects. Results of multidimensional scaling analysis of the models are…

Subjective Geographic Distance: A Multidimensional Comparison
Peer reviewed Peer reviewed
Lundberg, Ulf; Ekman, Gosta – Psychometrika, 1973
The interdistances between thirteen places situated in different parts of the world were estimated by 60 subjects. The estimates were analysed by Kruskal's multidimensional technique and, after a cosine transformation, by factor analysis. (Author)
Descriptors: Association (Psychology), Distance, Factor Analysis, Geographic Location
Computer Screen Design: Viewer Judgments.
Peer reviewed Peer reviewed
Grabinger, R. Scott – Educational Technology, Research and Development, 1993
Describes two studies that compared university students' judgments about the readability and studyability of two sets of computer screens: a set of model displays and a set of real screens copied from computer-assisted instruction programs. Relationships among viewers' preferences and field dependence/independence, conceptual style, and gender…
