Convergence of the Discrete-Time Compound Hawkes Processwith Exponential or Erlang Kernel

Lorick Huang,
Mahmoud Khabou

Abstract: Due to its clustering and self-exciting properties, the Hawkes process has been used extensively in numerous fields ranging from sismology to finance. Since data is often aquired on regular time intervals, we propose a piece-wise constant model based on a Discrete-Time Hawkes Process (DTHP). We prove that this discretetime model converges to the usual continuous-time Hawkes process as the time-step tends to zero.
