The markovian self-exciting process
SpletThe self-exciting point process with exponential exciting function is investigated using the immigration birth representation of the process. The counting distribution is derived explicitly and some simpler interval properties are given. SpletSelf-correcting models are used in ecology, forestry and other fields to model occurrences that are well-dispersed. Such models may be useful in describing births of species, for …

SpletWe introduce a multivariate point process describing the dynamics of the Bid and Ask price of a financial asset. The point process is similar to a Hawkes process, with additional constraints on its intensity corresponding to the natural … SpletBoth trends are directly quantifiable through the Markovian self-transition probabilities. It is shown that the Markovian memory can even imitate the evolution of a random process, regarding the long-term behavior of the frequencies of its binary states. This situation occurs when the associated binary state self-transition probabilities are ...
