Multi-response permutation procedure as an alternative to the analysis of variance: An SPSS implementation

Abstract

A permutation test typically requires fewer assumptions than does a comparable parametric counterpart The multi-response permutation procedure (MRPP) is a class of multivariate permutation tests of group difference useful for the analysis of experimental data. However, psychologists seldom make use of the MRPP in data analysis, in part because the MRPP is not implemented in popular statistical packages that psychologists use. A set of SPSS macros implementing the MRPP test is provided in this article. The use of the macros is illustrated by analyzing example data sets. Copyright 2006 Psychonomic Society, Inc.
