kerdiest (version 1.2)

saltriver: Data from the Salt River near Roosevelt, AZ, USA, for 1924-2006.

Description

The annual peak instantaneous flow of the Salt River near Roosevelt, AZ, USA, for 1924-2009. Data are in cfs (0.028317 m3/s); water year October-September. The data were examined in several papers related with extreme values in hydrology. Among others, they were analyzed by Anderson and Meerschaert (1998) and Dettinger and Diaz (2000), where they were fitted to a GEV and a GPD distribution. In Quintela del Rio (2011), a nonparametric analysis for this data set is made.
