Boolean Prediction Analysis is a method, based on Boolean algebra, for deriving prediction equations. This study examines some limitations of the method and adapts the method accordingly. The modification is achieved with the aid of a probabilistic measure of relevance, which also constitutes a simple tool for determining whether, and how, continuous variables can be dichotomized so as to render Boolean Prediction Analysis applicable. An illustrative application of the new technique is presented for purposes of comparison with the original approach.
