Multivariate integer-valued autoregressive models applied to earthquake counts

  title={Multivariate integer-valued autoregressive models applied to earthquake counts},
  author={Mathieu Boudreault and Arthur Charpentier},
  journal={arXiv: Applications},
In various situations in the insurance industry, in finance, in epidemiology, etc., one needs to represent the joint evolution of the number of occurrences of an event. In this paper, we present a multivariate integer-valued autoregressive (MINAR) model, derive its properties and apply the model to earthquake occurrences across various pairs of tectonic plates. The model is an extension of Karlis & Pedelis (2011) where cross autocorrelation (spatial contagion in a seismic context) is considered… 
A Periodic Bivariate Integer-Valued Autoregressive Model
In this paper, a bivariate integer-valued autoregressive model with periodic structure is introduced and studied in some detail. The model can be view as a generalization of the one considered in

On the theory of periodic multivariate INAR processes
In this paper a multivariate integer-valued autoregressive model of order one with periodic time-varying parameters, and driven by a periodic innovations sequence of independent random vectors is
Spatio-Temporal Low Count Processes with Application to Violent Crime Events
This work proposes to model the crime counts in each region using an integer-valued first order autoregressive process, and takes a Bayesian nonparametric approach to flexibly discover a clustering of these region-specific time series.
Thinning-based models in the analysis of integer-valued time series: a review
A comprehensive survey of recent developments in the field of integer-valued time series modelling, paying particular attention to models obtained as discrete counterparts of conventional autoregressive moving average and bilinear models, and based on the concept of thinning.
Modelling, Simulation and Inference for Multivariate Time Series of Counts Using Trawl Processes
This article presents a new continuous-time modelling framework for multivariate time series of counts which have an infinitely divisible marginal distribution. The model is based on a mixed moving

Multivariate count autoregression
A novel conceptual framework based on copulas is developed for studying the properties of multivariate count time series data with Poisson marginals, which avoids conceptual difficulties resulting from the joint distribution of discrete random variables.


Statistical Models for Earthquake Occurrences and Residual Analysis for Point Processes
Several classes of stochastic models for the origin times and magnitudes of earthquakes are discussed and the utility of seismic quiescence for the prediction of a major earthquake is investigated.
Multidimensional Residual Analysis of Point Process Models for Earthquake Occurrences
Residual analysis methods for examining the fit of multidimensional point process models are applied to point process models for the space–time–magnitude distribution of earthquake occurrences,
Stochastic Declustering of Space-Time Earthquake Occurrences
This article is concerned with objective estimation of the spatial intensity function of the background earthquake occurrences from an earthquake catalog that includes numerous clustered events in
In this paper, we indicate how integer-valued autoregressive time series Ginar(d) of ordre d, d ≥ 1, are simple functionals of multitype branching processes with immigration. This allows the
Existence and Stochastic Structure of a Non‐negative Integer‐valued Autoregressive Process
A simple criterion is given for the existence of a generalized integer‐valued autoregressive (GINAR(p)) process. We show that the GINAR(p) process is nothing but an AR(p) process. The spectral
Long-term earthquake clustering
SUMMARY We analyse statistically the long-term properties of several instrumental earthquake catalogues. Complete catalogues exhibit both short- and long-term clustering for earthquakes of all depth
Identifying Seismicity Levels via Poisson Hidden Markov Models
Poisson Hidden Markov models (PHMMs) are introduced to model temporal seismicity changes. In a PHMM the unobserved sequence of states is a finite-state Markov chain and the distribution of the
Integer‐Valued GARCH Process
Abstract.  An integer‐valued analogue of the classical generalized autoregressive conditional heteroskedastic (GARCH) (p,q) model with Poisson deviates is proposed and a condition for the existence
Foundations of Statistical Seismology
A brief account is given of the principles of stochastic modelling in seismology, with special regard to the role and development of stochastic models for seismicity. Stochastic models are seen as
