WebMay 19, 2024 · Motivated by the analysis of crime data in Bucaramanga (Colombia), we propose a spatiotemporal Hawkes point process model adapted to events living on linear networks. We first consider a non-parametric modelling strategy, for which we follow a non-parametric estimation of both the background and the triggering components. WebThe Hawkes process, which is generally defined for the continuous-time setting, can be described as a self-exciting simple point process with a clustering effect, whose jump rate depends on its entire history. Due to past events determining future developments of self-exciting point processes, the Hawkes model is generally not Markovian. In certain special …

Starting from kinetic models of criminal motion and target selection, we derive the probability density of anchor points using the …

WebWhat this means in plain English is that if we have a large sample (say the number of crimes per day over a year), if it is Poisson distributed we would expect about 27% of the days to have 1 crime. Doing the same for zero we would expect it to have under 14% zeroes.
