SPIChanges: Improves the Interpretation of the Standardized Precipitation Index Under Changing Climate Conditions (original) (raw)

Improves the interpretation of the Standardized Precipitation Index under changing climate conditions. The package uses the nonstationary approach proposed in Blain et al. (2022) <doi:10.1002/joc.7550> to detect trends in rainfall quantities and to quantify the effect of such trends on the probability of a drought event occurring.
