Theoretical Foundations of Ordinal Multidimensional Scaling, Including Internal and External Unfolding

Statistics Theory 2025-06-19 v3 Statistics Theory

Abstract

We provide a comprehensive theory of multiple variants of ordinal multidimensional scaling,including internal unfolding and external unfolding. We first follow Shepard (1966) and work in a continuum model to gain insight. We then follow Kleindessner and von Luxburg (2014) and work in an asymptotic discrete setting.
