- Description
The data set is a record of the lowest annual water levels on the Nile river during 622-1284 measured at the island of Roda, near Cairo, Egypt. There is domain knowledge suggesting a change point in year 715 due to an upgrade in ancient sensor technology to the nilometer. There is also evidence that anomalies in the Nile record can be used to infer years of El Nino (Eltahir and Wang, 1999). The installation of the nilometer is the most visually noticeable change in the time series.
