Some Uniqueness Results for PARAFAC2.
ten Berge, Jos M. F.; Kiers, Henk A. L.
Psychometrika, v61 n1 p123-32 Mar 1996
Some uniqueness properties are presented for the PARAFAC2 model for covariance matrices, focusing on uniqueness in the rank two case of PARAFAC2. PARAFAC2 is shown to be usually unique with four matrices, but not unique with three unless a certain additional assumption is introduced. (SLD)
