Abstract

This documentation describes the implementation of Bayesian Network on Hiroshima Nagasaki atomic bomb survivor data using R software Bayesian networks a state-of-the art representation of probabilistic knowledge by a graphical diagram has emerged in recent years as essential for pattern recognition and classification in the healthcare field Unlike some data mining techniques Bayesian networks allow investigators to combine domain knowledge with statistical data This tailored discussion presents the basic concepts of Bayesian networks and its use for building a health risk model on Epidemiological data The main objectives of our study is to find interdependencies between various attributes of data and to determine the threshold value of radiation dosage under which death counts are negligible
