ADDITIVE 2-MODE CLUSTERING - THE ERROR-VARIANCE APPROACH REVISITED

The additive clustering approach is applied to the problem of two-mode clustering and compared with the recent error-variance approach of Ec kes and Orlik (1993). Although the schemes of the computational algori thms look very similar in both of the approaches, the additive cluster ing has been shown to have several advantages. Specifically, two techn ical limitations of the error-variance approach (see Eckes and Orlik 1 993, p. 71) have been overcome in the framework of the additive cluste ring.
