A New Heterogeneous Multidimensional Unfolding Procedure
Peer reviewed Peer reviewed
Direct linkDirect link
Park, Joonwook; Rajagopal, Priyali; DeSarbo, Wayne S. – Psychometrika, 2012
A variety of joint space multidimensional scaling (MDS) methods have been utilized for the spatial analysis of two- or three-way dominance data involving subjects' preferences, choices, considerations, intentions, etc. so as to provide a parsimonious spatial depiction of the underlying relevant dimensions, attributes, stimuli, and/or subjects'…

A Model-Based Approach for Visualizing the Dimensional Structure of Ordered Successive Categories Preference Data
Peer reviewed Peer reviewed
Direct linkDirect link
DeSarbo, Wayne S.; Park, Joonwook; Scott, Crystal J. – Psychometrika, 2008
A cyclical conditional maximum likelihood estimation procedure is developed for the multidimensional unfolding of two- or three-way dominance data (e.g., preference, choice, consideration) measured on ordered successive category rating scales. The technical description of the proposed model and estimation procedure are discussed, as well as the…
