WebJul 1, 2024 · The Hawkes process [1], [2] is a self-exciting point process for which the arrival of one event increases the probability of occurrence of new ones. Let us consider a probability space on which is defined a counting process with random independent identically distributed marks denoted by . In probability theory and statistics, a Hawkes process, named after Alan G. Hawkes, is a kind of self-exciting point process. It has arrivals at times $${\textstyle 0<\cdots }$$ where the infinitesimal probability of an arrival during the time interval $${\textstyle [t,t+dt)}$$ See more Hawkes processes are used for statistical modeling of events in mathematical finance, epidemiology, and other fields in which a random event exhibits self-exciting behavior.
