Classification of schizo-affective patients by multidimensional scaling and cluster analysis.
269 patients with schizophrenia, schizo-affective or affective disorders admitted to a hospital in Zürich were examined by the AMP system and the syndrome checklist of Wing and co-workers. The data were analyzed using a special set-theoretical similarity measure for nonlinear graduations, multidimensional scaling to achieve a metric representation of the similarity matrices, and a cluster analysis, originally described by Meisel in 1972.
