The joint spatial representation of multiple variable batteries collected in marketing research

Marketing research studies pertaining to market segmentation, competitive m arket structure, and product/service positioning often involve the collecti on of multiple batteries of measurements from the same set of respondents ( e.g., preferences, attribute ratings, demographics, proximity judgments). V arious multidimensional scaling (MDS) and spatial methods have been used in the analysis of these variable batteries separately, but not much effort h as been expended in attempting to relate the individually derived spatial s tructures. The authors propose a new latent structure MDS procedure that is devised to represent jointly the structure in multiple batteries (preferen ces, proximities, and brand attribute ratings) of variables collected acros s the same set of respondents. The authors present the technical structure of the proposed maximum likelihood-based model and conceptually compare it with other related spatial MDS models. The authors present an illustration of the procedure with respect to the analysis of published proximity, prefe rence, and brand ratings data collected from consumers who evaluated ten br ands of soft drinks.
