The Analysis of Averages and the Analysis of Variance

Abstract

In the analysis of averages and analysis of variance of a balanced array, repeated sweeping out of margin summaries has several advantages. These include the use of resistant summaries as alternatives to the mean, an exploratory emphasis, and computational convenience. The advantages offset the computational inefficiency of the sweep method relative to the Yates algorithm. However, analysis of averages and variance is not straightforward using the sweep function commonly found in data analysis software. Part I describes an invariant data structure and enhancements to sweep to provide computation of degrees of freedom and organization and annotation of a sequence of sweeps. The usual analysis of variance and median polish are defaults for the enhanced functions. Part II and the Appendix detail the specific implementation in S.
