Evidence Synthesis Using Bayesian Belief Networks

  • Chapter
  • First Online:
Evidence Synthesis in Healthcare

Abstract

Bayesian belief networks (BBNs) are graphical tools for reasoning with uncertainties. In BBNs, uncertain events are represented as nodes and their relationships as links, with missing links indicating conditional independence. BBNs perform belief updating when new information becomes available; they can handle incomplete information and capture expert judgments along with data. BBNs provide a normative framework for synthesizing uncertain evidence.
