Point process models are useful for describing phenomena occurring at random locations and/or times. Following a review of basic concepts, some important models are surveyed including Poisson processes, renewal processes, Hawkes processes, and Markovian point processes. Techniques for estimation, simulation and residual analysis for point processes are also briefly discussed.A point process is a random collection of points falling in some space. In most applications, each point represents the time and/or location of an event, such as a lightning strike or earthquake. When modeling purely temporal data, the space in which the points fall is simply a portion of the real line.
