Estimation of Residential Radon Concentration in Pennsylvania Counties by Data Fusion
share
A data fusion method for the estimation of residential radon level distribution in any Pennsylvania county is proposed. The method is based on a multi-sample 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.
