Bayesian Decision Analysis I - Basics

Location – (Web PDC)

Instructions regarding how to log onto the web PDC and the conference call phone number, as well as handouts, will emailed to the registered participants at least twenty four hours prior to the web PDC.

Instructor:

Dr. Paul Hewett Ph.D. CIH

Course Description

This 2.5 hour webinar PDC consists of Part I of a two part introduction to Bayesian Decision Analysis (BDA). BDA refers to the application of Bayesian statistical methods to IH “decision making”: i.e., the classification of exposures into exposure control categories, such as the AIHA exposure control categories, UK or ILO Control Banding categories, or pharmaceutical exposure control bands. (See the list of Prerequisites.)

Part I covers the following: basic methodology and calculations; assumptions, cautions and issues, and the use of the freeware program IHDataAnalyst-LiteEdition to analyze and interpret data using BDA.

The webinar will last 2.5 hours, with an additional 30 minutes for followup questions and clarifications. Each participant will receive an email confirming participation in the PDC.

Learning Objectives

  • Understanding of Bayesian Decision Analysis (BDA) methodology.
  • Ability to use the freeware program IHDataAnalyst-LiteEdition to calculate the Prior, Likelihood, and Posterior decision charts.
  • Ability to quantify “professional judgment” using a Prior Decision Chart.
  • Understanding of how BDA and the decision charts can be used to make IH decisions.
  • Understanding of how BDA can be integrated into the AIHA or similar exposure assessment and management model.

Prerequisites

  • Participation in the webinar PDC “IH Stats I – Basics” or a strong background in IH statistics.
  • Familiarity with the AIHA Exposure Assessment and Management Model (see the AIHA monograph “A Strategy for Assessing and Managing Occupational Exposures”, 3rd Edition (2006)
  • Working knowledge of the IHDataAnalyst (full or Student Edition).
  • Recommended reading prior to the WebPDC:
    • Hewett, P., Logan, P., Mulhuasen, J., Ramachandran, G., and Banerjee, S.: Rating Exposure Control Using Bayesian Decision Analysis. Journal of Occupational and Environmental Health 3:568-581 (2006).
    • Chapter 21 in the AIHA monograph “A Strategy for Assessing and Managing Occupational Exposures”, 3rd Edition (2006).
