Abstract: Abstract In Chap. 5 , principalThree-Way Principal Component Analysis (3WPCA) component analysisPrincipal Component Analysis (PCA) (PCA) was introduced as the reduced rank approximationReduced rank approximation of a data matrix. This matrix should be noted to be a two-way array of rows × columnsColumn. We often encounter three-way data arraysThree-way data array, however, an example of which is a set of scores of examinees for multiple tests administered on different occasions. These scores form a three-way array of examinees × tests × occasions. Modified PCAPrincipal Component Analysis (PCA) procedures specified for similar three-way data are known as three-way PCA (3WPCAThree-Way Principal Component Analysis (3WPCA)). Popular 3WPCA procedures are introduced in this chapter.
