Constrained DEDICOM.

Kiers, Henk A. L.; Takane, Yoshio

Psychometrika, v58 n2 p339-55 Jun 1993

The DEcomposition into DIrectional COMponents (DEDICOM) method for analysis of asymmetric data gives representations that are identified only up to a non-singular transformation. To identify solutions, it is proposed that subspace constraints be imposed on the stimulus coefficients. Procedures are discussed for several cases. (SLD)
