The Direct Product Model for the MTMM Matrix Parameterized as a Second Order Factor Analysis Model.
Peer reviewed Peer reviewed
Wothke, Werner; Browne, Michael W. – Psychometrika, 1990
The composite direct-product model for the multitrait-multimethod (MTMM) matrix is reparamaterized as a second-order factor analysis model. This process facilitates the use of widely available computer programs--LISREL and LISCOMP--for fitting the model. If bounds on phi and theta are not imposed to avoid inadmissible values, convergence problems…

An Efficient Algorithm for TUCKALS3 on Data with Large Numbers of Observation Units.
Peer reviewed Peer reviewed
Kiers, Henk A. L.; And Others – Psychometrika, 1992
A modification of the TUCKALS3 algorithm is proposed that handles three-way arrays of order I x J x K for any I. The reduced work space needed for storing data and increased execution speed make the modified algorithm very suitable for use on personal computers. (SLD)
