Abstract:
|
The CDC conducts the National Health Interview Survey (NHIS) and maintains a database of air quality estimates from USEPA's Bayesian space-time Downscaler (DS) fusion model, which combines output from the Community Multi-scale Air Quality model with monitor-based measurements from USEPA's Air Quality System. Specifically, DS-based annual predictions and estimated standard errors of 24-hour average PM2.5 concentrations (µg/m3) for 2010 U.S. Census tract centroid locations were linked to NHIS data. Estimated standard errors varied across locations, depending on distances to air monitors. Nonparametric regression with measurement errors was used to associate population health with annual air quality estimates. A deconvolution estimator with heteroscedastic error in R package "Decon" was used. Bootstrap confidence interval (CI) bands for "Decon" results were generated using R package "Boot". Several alternative methods to compute CI bands were applied and compared. Point and CI estimates across methods were compared for models with and without measurement errors.
