This study investigates similarities and differences between Tucker3 models with two components for each mode and Parafac models with two components. If the corearray of the 2 x 2 x 2 Tucker3 model is of rank 2 the solutions contain exactly the same information, but they do not when the rank of the corearray is three. Two illustrative applications show the effect the different corearrays have on the solutions and their interpretability. (C) 2010 Elsevier B.V. All rights reserved.
