Estimation of residential radon concentration in Pennsylvania counties by data fusion

Abstract

A data fusion method for the estimation of residential radon level distribution in any Pennsylvania county is proposed. The method is based on a multisample density ratio model with variable tilts and is applied to combined radon data from a reference county of interest and its neighboring counties. Beaver county and its four immediate neighbors are taken as a case in point. The distribution of radon concentration is estimated in each of six periods, and then the analysis is repeated combining the data from all the periods to obtain estimates of Beaver threshold probabilities and the corresponding confidence intervals.

Estimation of Tail Probabilities by Repeated Augmented Reality

“…The estimation of tail probabilities from fused residential radon data has been studied recently in Zhang et al [11,14] by using the density ratio model with variable tilts. There a given radon sample from a county of interest was fused with radon samples from neighboring counties.…”

“…Residential radon test levels were collected by PA Department of Environmental Protection (PADEP) statewide in the period from 1990 to 2007. See Zhang et al [ 11 ] for a study of indoor radon concentrations from Beaver County and its neighboring counties in PA.…”

“…The appendix addresses the density ratio model (11) for m + 1 data sources. Thus, we deal with the density ratio model more generally where X 0 is fused with m computer-generated samples.…”

On the Probabilities of Environmental Extremes

“…06 . A different approach to residential radon exceedances using fused county data is studied in Zhang et al (2020a,b) [11,12], employing a density ratio model with variable tilt functions.…”
