| Abstract The permutation test follows directly from the procedure in a comparative experiment, does not depend on a known distribution for error, and is sometimes more sensitive to real effects than the corresponding parametric tests. Despite its advantages, the permutation test is seldom (if ever) applied to factorial designs because of the computational load that they impose. The paper proposes two methods to limit the computation load. Firstly, we show that orthogonal contrasts limit the computational load and secondly, that, when combined with Gill’s (2007) algorithm, the factorial permutation test is both practical and efficient. For within-subjects designs, the factorial permutation test is equivalent to ANOVA when the latter’s assumptions have been met. For between-subjects designs, the factorial test is conservative. |
