This talk contains two parts. Firstly, we consider estimation of intensity function for a spatial point pattern based on spatially aggregated count data. A standard approach for estimating the intensity function is to use a kernel estimator. However, when data are only available in a spatially aggregated form with the numbers of events available in geographical subregions, traditional methods become infeasible. In this research, a kernel-based method is proposed to produce a smooth intensity function based on aggregated data. Secondly, we consider testing a spatial signal based on data obtained by aggregating an image into several subregions. Our method utilizes a nonparametric testing procedure called enhanced false discovery rate originally developed to detect a spatial signal from an image. Some numerical examples will be given to demonstrate the effectiveness of the proposed methods
