Statistical Tools for Climate Change Analysis
Author: Sadikul Islam


Overview

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.

Installation

Quick Example

library(climatestatsr)

# Mann-Kendall trend test
set.seed(42)
temp   <- 14 + 0.025 * seq_len(50) + stats::rnorm(50, 0, 0.4)
result <- mk_test(temp)
print(result)

# Sen's warming rate per decade
ss <- sens_slope(y = temp)
cat("Warming:", round(ss$slope_decade, 3), "deg C per decade\n")

# SPI drought index
precip <- stats::rgamma(360, shape = 2, scale = 30)
spi3   <- spi(precip, scale = 3)

# GEV extreme value analysis
ann_max <- rgev_sim(50, mu = 35, sigma = 4, xi = 0.1)
gev     <- fit_gev(ann_max)
rp      <- return_period(gev, c(10, 50, 100))
print(rp)
