The Hawkes process, or otherwise known as the self-exciting process, is an extension of Poisson processes that aims to explain excitatory interactions (Hawkes,1971). What makes the term self-excitation worthy of its name is typically not the occurrence of the initial event, but the in-tensification of further events. We seek to ...

Web6.1.2 Rate Inversion Method. The second method for generating a non-stationary Poisson process is through the rate inversion algorithm. In this method, a \(\lambda = 1\) Poisson process is generated, and the inverse of the mean arrival rate function is used to re-scale the times of arrival to the appropriate scale. This section does not discuss the theory …
