TESTING ORDERED CATEGORICAL DATA IN $ 2 \times k $ TABLES BY THE STATISTICS WITH ORTHONORMAL SCORE VECTORS
L. A. L. W. Jayasekara, Takashi Yanagawa · Bulletin of informatics and cybernetics · 1995
A class of tests is proposed for detecting the difference of two populations in an ordinal categorical table. Characteristics of the proposed tests are studied. It will be shown that the new tests may have higher powers for a class of non-linear responses than the other conventional tests.
