Rating Exposure Control Using Bayesian Decision Analysis

In volume 3, issue 10 of Journal of Occupational and Environmental Hygiene, some incorrect text appeared in Rating Exposure Control Using Bayesian Decision Analysis by Paul Hewett, et al., pages 568–581. The correct text is shown below.

Page 571

The Bayesian approach to statistics and decision making is based on the equation developed by the Reverend Thomas

Bayes and published in 1763.

Page 572

The posterior distribution probability P(lnG_i, lnD_i|data) is calculated using Eq. 1 and represents the mathematical combination of the prior distribution and the likelihood distribution, and reflects our final decision probability regarding the ith exposure profile.

For this article we used the following integration boundaries:

Dmin = 1.05  Dmax = 4

Gmin = 0.0005 · L_TWA Gmax = 5 · L_TWA

Page 580

Similarly, for Gmin our recommended default setting is 1/2000th the cutoff for the OEL.
