How Changing the Ozone Standard Might Affect Respiratory Mortality

We present a risk assessment analysis of the potential effect that various regulatory standards for ozone may have on the incidence of respiratory-related mortality. The analysis uses roll-back functions as models for the potential effect of regulatory standards. The statistical methods are based on hierarchical Bayesian models. The objective is to obtain estimates of the effects of various regulatory standards, estimates of their variability, and the effects of various modeling assumptions on those estimates. We also introduced a parametric rollback approach.
