Abstract This paper presents a general approach for fitting the ADCLUS (Shepard and Arabie 1979; Arabie, Carroll, DeSarbo, and Wind 1981), INDCLUS (Carroll and Arabie 1983), and potentially a special case of the GENNCLUS (DeSarbo 1982) models. The proposed approach, based largely on a separability property observed for the least squares loss function being optimized, offers increased efficiency and other advantages over existing approaches like MAPCLUS (Arabie and Carroll 1980) for fitting the ADCLUS model, and the INDCLUS method for fitting the INDCLUS model. The new procedure (called “SINDCLUS”) is applied to three sets of empirical data to demonstrate the effectiveness of the SINDCLUS methodology. Finally, some potentially useful extensions are discussed.
