Aligned Rank Transform for Nonparametric Factorial Analysis
Description
An implementation of the Aligned Rank Transform technique for
factorial analysis (see references below for details) including models with
missing terms (unsaturated factorial models). The function first
computes a separate aligned ranked response variable for each effect of the
user-specified model, and then runs a classic ANOVA on each of the aligned
ranked responses. For further details, see Higgins, J. J. and Tashtoush, S.
