Statistical Tools for Climate Change Analysis
Author: Sadikul Islam
climatestatsr is a comprehensive R package providing statistical functions
for climate change research. It covers temporal trend analysis, spatial
analysis, extreme event assessment, standardised climate indices, and formal
detection-attribution methods.
