The Problem of Local Optimality with OSMOD.

Otsu, Tatsuo; Saito, Takayuki

Psychometrika, v55 n3 p517-18 Sep 1990

A revision of the initialization strategy is suggested for OSMOD, a method of nonlinear principal component analysis for multivariate nominal and/or ordinal data. The revision is effective in diminishing the possibility of obtaining locally optimal solutions with categorical data provided by the original version of OSMOD. (SLD)
