Suppose that Points A to G in Figure 3 represent the locations at which some events of a certain type (e.g., traffic accidents) occur along a network illustrated in Figure 3. Assuming that the density of events at any point in the network is influenced by all events within 3 units of distance measured along the network from that point in the Cartesian coordinate system to which the road network is referenced, answer the following questions. Events (represented by darkly shaded points) in a road network (represented by a line segment). Note that the pair of numbers associated with each point indicates the location of that point on a Cartesian coordinate system. 1-(1) Define a triangular kernel that can be used for event density estimation under the assumption Described above. (2) Calculate the density of events at Point X using the kernel defined above. (3) Calculate the density of events at Point Y using the kernel defined above.
