Multidimensional Unfolding: Some Geometrical Solutions
D. W. McElwain, John A. Keats · Psychometrika · 1961
A method is proposed whereby the distribution of stimuli and subjects can be derived directly from the subjects' rankings of the stimuli. The solution for four stimuli is presented with examples and suggestions for the solution of problems involving more stimuli. The model is intuitively attractive and is likely to prove useful when direct solutions for larger number of stimuli are available.
