The Direct Product Model for the Mtmm Matrix Parameterized as a Second Order Factor Analysis Model
Werner Wothke, Michael W. Browne · Psychometrika · 1990
The composite direct product model for the multitrait-multimethod matrix is reparameterized as a second-order factor analysis model. This facilitates the use of widely available computer programs such as LISREL and LISCOMP for fitting the model.
