Spatial Smoothing of Geographically Aggregated Data, with Application to the Construction of Incidence Maps
地理聚合数据的空间平滑及发病率地图构建
We address the commonly encountered situation in spatial statistics where data such as counts of incidences of a certain disease are available only in geographically aggregated form. We develop fairly general models and propose a modified version of the locally weighted least squares method to recover the unknown smooth spatial function that is assumed to generate the observations. In the special case of count data, the target function is the intensity function, conditional…
