Joint structural break detection and parameter estimation in high-dimensional nonstationary VAR models

A Safikhani, A Shojaie - Journal of the American Statistical …, 2022 - Taylor & Francis
Assuming stationarity is unrealistic in many time series applications. A more realistic
alternative is to assume piecewise stationarity, where the model can change at potentially …

Nonparametric Bayesian estimation for multivariate Hawkes processes

S Donnet, V Rivoirard, J Rousseau - The Annals of statistics, 2020 - JSTOR
This paper studies nonparametric estimation of parameters of multivariate Hawkes
processes. We consider the Bayesian setting and derive posterior concentration rates. First …

dynamic of a motoneuron between its spikes, taking into account the spikes from other …

Numerical method for means of linear Hawkes processes

Z Li, L Cui - Communications in Statistics-Theory and Methods, 2020 - Taylor & Francis
Linear Hawkes processes are widely used in many fields and means are the basic and
critical information of them. However, there is little research on linear Hawkes processes' …

Hawkesian graphical event models

X Yu, K Shanmugam, D Bhattacharjya… - International …, 2020 - proceedings.mlr.press
Graphical event models (GEMs) provide a framework for graphical representation of
