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.
