Non-Supervised Regional Frequency Analysis R package nsRFA version 0.7-17 CRAN Task View: Environmetrics (https://CRAN.R-project.org/view=Environmetrics) CRAN Task View: Hydrology (https://CRAN.R-project.org/view=Hydrology) A collection of statistical tools for objective (non-supervised) applications of the Regional Frequency Analysis methods in hydrology. The package refers to the index-value method and, more precisely, helps the hydrologist to: (1) regionalize the index-value; (2) form homogeneous regions with similar growth curves; (3) fit distribution functions to the empirical regional growth curves. Most of the methods are those described in the Flood Estimation Handbook (Centre for Ecology & Hydrology, 1999, ISBN:9781906698003). Homogeneity tests from Hosking and Wallis (1993) <doi:10.1029/92WR01980> and Viglione et al. (2007) <doi:10.1029/2006WR005095> are available.
