WebPoisson process, however, λ is deterministic; i.e. λ(t) depends only on t. A stationary Poisson process has constant conditional rate: λ(t) = α, for all t. This model posits that the risk of an event is the same at all times, regardless of how frequently such events have occurred previously. For a non-stationary Poisson process, λ(t) is some the long gallery powis castleWebHawkes models. Chavez-Demoulin et al. [7] studied value-at-risk. Errais et al.
