“…We note that if k = 0, then f s (x, y) = 0 is a constant function in F 0 . Similarly to the result on the temporal point process in [18], we can show that the mapping from the spatial point process space S to the space of the smoothed process F is a bijection. Mathematical details are given in Appendix B.…”

“…In this paper, the transformed function is called the smoothed function or the smoothed point process. Xu et al [18] first adopted a Gaussian kernel function for the temporal point process within a given domain, and then used the conventional L 2 metric on the smoothed functions. However, this distance involves numerical integration as there is no closed-form expression available in general.…”

“…To address these issues, we propose a new, rank-based likelihood framework for modeling the spike train data. Our framework is motivated by recent developments in center-outward ranks on point process [5][6][7]. Our proposed model describes the likelihood of a spike train as the product of two terms.…”
