%description
A comprehensive collection of statistical functions for climate change
research. Provides tools for temporal trend detection based on the
Mann-Kendall (MK) test (Mann 1945 <doi:10.2307/1907187>; Kendall 1975,
ISBN:0852641990) and Sen's slope (Sen 1968 <doi:10.2307/2285891>), spatial
autocorrelation using Moran's I (Moran 1950 <doi:10.2307/2332142>),
extreme value analysis using the Generalised Extreme Value (GEV)
distribution and Peaks-Over-Threshold (POT) method (Coles 2001
<doi:10.1007/978-1-4471-3675-0>), standardised drought indices including
the Standardised Precipitation Index (SPI; McKee et al. 1993) and the
Standardised Precipitation Evapotranspiration Index (SPEI; Vicente-Serrano
et al. 2010 <doi:10.1175/2009JCLI2909.1>), and formal
detection-attribution methods via optimal fingerprint regression and
Empirical Orthogonal Function (EOF) analysis (Allen and Tett 1999
<doi:10.1007/s003820050291>), and apparent temperature via the heat index
(Steadman 1979 <doi:10.1175/1520-0450(1979)018%%3C0861:TAOSPI%%3E2.0.CO;2>).
Suitable for both station-level time series and gridded climate fields.
