Modified Mann-Kendall trend test for hydrological time series under the scaling hypothesis and its application

Hydrological Sciences Journal, 2020
The existence of persistence contaminates the results of the Mann-Kendall (MK) trend test. This paper proposes an improved MK test for hydrological data with both positive and negative persistence. To this end, the variance and distribution patterns of S

Analyzing Temperature, Precipitation, and River Discharge Trends in Afghanistan’s Main River Basins Using Innovative Trend Analysis, Mann–Kendall, and Sen’s Slope Methods

Climate
Afghanistan, a nation already challenged by geopolitical and environmental pressure, faces severe climate change impacts, evident through rising temperatures, decreasing precipitation, and reduced river discharge.

A Contextual Mann‐Kendall Approach for the Assessment of Trend Significance in Image Time Series

Transactions in GIS, 2011
AbstractOne of the most common problems in estimating trends in image time series is the presence of contaminants such as clouds. There are many techniques for estimating robust trends but evaluating the significance of the trends can be difficult due to this increased variance. This article presents a novel approach called the Contextual Mann‐Kendall (

Mann-Kendall test with missing data

2009
Summary: The Mann-Kendall test [see \textit{H. B. Mann}, Econometrika 13, 245--259 (1945; Zbl 0063.03770)] for testing a time trend monotone in the variable is written as a \(U\)-statistic whose kernel is modified to take into account the missing data.

Determining the most accurate program for the Mann-Kendall method in detecting climate mutation

Theoretical and Applied Climatology, 2020
In the detection of abrupt changes in a time sequence using the Mann-Kendall method, two programs (PRGM1 and PRGM2) were found to provide two different mutation points for the same temperature sequence. The code of PRGM1 was programmed according to the step-by-step direction of the Mann-Kendall method described in the original report, and PRGM2 is the ...
