ETAS is an R package for fitting the space-time ETAS model to an earthquake catalog using the stochastic declustering approach introduced by Zhuang, Ogata, and Vere-Jones (2002). The package provides two classes and several functions to facilitate data preparation, model fitting and some simple diagnostic checks. The present paper is a description of the package and illustrates modeling earthquake data using the space-time ETAS model.}, number={1}, journal={Journal of Statistical Software, Code Snippets}, author={Jalilian, Abdollah}, year={2019}, pages={1–39} }
