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.

通过数据融合估算宾夕法尼亚县住宅氡浓度

提出了一种用于估计宾夕法尼亚州任何县的住宅氡水平分布的数据融合方法。该方法基于具有可变倾斜度的多样本密度比模型，并应用于来自感兴趣的参考县及其邻近县的组合氡数据。海狸县及其四个近邻就是一个例子。氡浓度分布在六个时期的每一个估计，然后结合所有时期的数据重复分析以获得Beaver阈值概率的估计和相应的置信区间。
