Abstract:
In this paper we present a technique to derive rules describing contrast sets. Contrast sets are a formalism to represent groups di ferences. We propose a novel approach to describe directional contrasts using rules where the contrasting e ect is partitioned into pairs of groups. Our approach makes use of a directional Fisher Exact Test to a nd signi cant di erences across groups. We used a Bonferroni within search adjustment to control type I errors and a pruning technique to prevent derivation of non signi cant contrast set specializations.
