MannKendallTest
The Mann-Kendall test, or Mann-Kendall trend test, is a nonparametric statistical method used to detect monotonic trends in a time-ordered sequence of measurements. It is widely applied in hydrology, climatology, and environmental sciences to identify whether a variable such as rainfall, stream flow, temperature, or pollutant concentration shows a consistent increase or decrease over time without assuming a specific distribution for the data.
The test operates by examining all pairs of observations and counting the number of pairs that show
Variants and adjustments exist to handle common data characteristics. The Seasonal Mann-Kendall test extends the method
Limitations include reduced power with small samples and sensitivity to autocorrelation. The Mann-Kendall test can indicate
