A Test for a Neglected Source of Variation: The Individual Difference by Repeated Measures Interaction.
Draper, John F.; Porter, Andrew C.
The repeated measures design is of importance to those interested in doing learning studies concerned with repeated trials on a single type of task, repeated trials on different tasks, or both together crossed with and following different treatments. In doing analysis of variance with such data it is assumed that the data fits an additive model. Since the existence of an unrecognized independent variable may, in some cases, imply a violation of the assumption of additivity, a test for non-additivity is needed. Such a test is illustrated.
