Research Abstract	A method for spatial data analysis focused on distributions of incidence points is developed to recognize the spatial trend in critical events. Two probability density functions are based on the distributions of the known points of the past and unknown points by kernel density estimation method, and the difference between these functions is formulated as integrated squared error. A method that approximates the distribution of known points by unknown ones and its solution using point data are proposed by minimizing the spatial difference between the two distributions.
