The data is obtained from the website of the book [Time Series +Analysis by State Space Methods](http://www.ssfpack.com/DKbook.html) by Durbin +and Koopman. The data is also available in the R ``datasets`` package, which +is part of R and is therefore licensed under version 2 of the [GNU Public +License](https://www.r-project.org/COPYING). The data file produced from this +data (``nile.json``) is therefore licensed under GPLv2 as well. + +A potential change point occurs in 1898 with the introduction of a dam. + +Note that this is not the Nile dataset used in other change point papers, +which covers a period from 622 to 1284 AD (see e.g. Witcher et al. (2002)). +That dataset, [available +here](https://web.archive.org/web/20000815223740/http://lib.stat.cmu.edu/S/beran), +has been used in many papers to detect the introduction of a nilometer in the +year 715 AD. + + |
