It is shown that two different theories of this type are always available to explain crossover interaction in a 2x2 table. For example, one theory may say that a good outcome occurs when there is an approximate match between values associated with the independent variables, and the other theory that a good outcome occurs when the total of values associated with the independent variables is either decisively small or large, with poorer outcome resulting from intermediate values. | | Publisher | Australian Society for Operations Research | | Publisher City | Canberra | | ISSN | 0812-860X | | Journal Title | ASOR Bulletin | | Journal Volume (Issue) | 28(3) | | Page Range | 25-29 | | Notes | Available from http://www.asor.org.au/publication/page.php?page=1 |
