State-dependent Hawkes processes and their application to limit order book modelling
نویسندگان
چکیده
We study statistical aspects of state-dependent Hawkes processes, which are an extension processes where a self- and cross-exciting counting process state fully coupled, interacting with each other. The excitation kernel the depends on that, reciprocally, switches when there is event in process. first establish existence uniqueness explain how they can be simulated. Then we develop maximum likelihood estimation methodology for parametric specifications apply to high-frequency limit order book data, allowing us build novel model that captures feedback loop between flow shape book. estimate two model, using bid–ask spread queue imbalance as variables, find effects strongly state-dependent. Additionally, endogeneity flow, measured by magnitude excitation, also state-dependent, being more pronounced disequilibrium states

متن کاملCentral Limit Theorem for Nonlinear Hawkes Processes
Hawkes process is a self-exciting point process with clustering effect whose jump rate depends on its entire past history. It has wide applications in neuroscience, finance and many other fields. Linear Hawkes process has an immigration-birth representation and can be computed more or less explicitly. It has been extensively studied in the past and the limit theorems are well understood. On the...
متن کاملLong-Time Behavior of a Hawkes Process-Based Limit Order Book
Hawkes processes provide a natural framework for modelling dependencies between the intensities of point processes. In the context of order-driven financial markets, the relevance of such dependencies has been amply demonstrated from an empirical, as well as theoretical, standpoint. In this work, we build on previous empirical and numerical studies and introduce a mathematical model of limit or...
متن کاملSome limit theorems for Hawkes processes and application to financial statistics
In the context of statistics for random processes, we prove a law of large numbers and a functional central limit theorem for multivariate Hawkes processes observed over a time interval [0, T ] when T → ∞. We further exhibit the asymptotic behaviour of the covariation of the increments of the components of a multivariate Hawkes process, when the observations are imposed by a discrete scheme wit...
متن کاملModelling Reciprocating Relationships with Hawkes Processes
We present a Bayesian nonparametric model that discovers implicit social structure from interaction time-series data. Social groups are often formed implicitly, through actions among members of groups. Yet many models of social networks use explicitly declared relationships to infer social structure. We consider a particular class of Hawkes processes, a doubly stochastic point process, that is ...
