Abstract

A stimulus-response LCS, called EpiCS, based upon the BOOLE and NEWBOOLE paradigms, was developed to work in single-step environments in which the goal is to generalize clinical decision rules from medical data by means of building explanatory and predictive models. This paper addresses the scalability of EpiCS to a large database, the Fatal Accident Reporting System (FARS), which is a large prospective database supported by the National Highway Traffic Safety Administration (NHTSA) of Transportation. This investigation used 1998 FARS data, the most recent complete year's data available at this time. The performance of EpiCS in building explanatory and predictive models compared very favorably with a decision tree inducer and logistic regression applied to these tasks.
