Block bootstrap for Mann–Kendall trend test of serially dependent data
Hydrological Processes, 2012AbstractMann–Kendall (MK) test for trend detection must be modified when the data are serially correlated, to prevent the detection of false trends. Various approaches are developed for this purpose, such as prewhitening, trend‐free prewhitening, variance correction and block bootstrap. Each method has its own Type I and Type II errors.

On the effectiveness of Mann-Kendall test for detection of software aging
2013 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2013Software aging (i.e. progressive performance degradation of long-running software systems) is difficult to detect due to the long latency until it manifests during program execution. Fast and accurate detection of aging is important for eliminating the underlying defects already during software development and testing.

A Pilot Protection Scheme of Hybrid DC Line based on Mann-Kendall Test
2020 IEEE Sustainable Power and Energy Conference (iSPEC), 2020The hybrid DC transmission system combines the advantages of traditional HVDC and flexible DC transmission systems, which is an inevitable trend in the development of DC systems. Aiming at the problem that traditional DC pilot differential protection is susceptible to distributed line capacitance, a hybrid DC line pilot protection method based on Mann ...

Mann-Kendall test with missing data
2009Summary: 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.

Exact distribution of the Mann–Kendall trend test statistic for persistent data
Journal of Hydrology, 2009The distribution-free Mann-Kendall test is widely used for the assessment of significance of trends in many hydrologic and climatic time series. Previous studies have suggested both exact and approximate formulas for the calculation of the variance of the test statistic when the data are serially correlated.

Improved Seasonal Mann–Kendall Tests for Trend Analysis in Water Resources Time Series
2016Nonparametric statistical procedures are commonly used in analyzing for trend in water resources time series (Chapter 23, Hipel and McLeod in Time series modelling of water resources and environmental systems. Elsevier, New York, 2005 [10]). One popular procedure is the seasonal Mann–Kendall tau test for detecting monotonic trend in seasonal time ...

Rainfall Trend Analysis by Mann-Kendall Test: A Case Study of Andong Dam Basin
Crisis and Emergency Management: Theory and Praxis, 2020Rainfall has become a primary concern for flood control and effective water resources management. It is predicted that the reduction of available water resources due to climate change will exert a severe influence on human life. This study conducted a trend analysis on the annual rainfall, monthly rainfall, and monthly maximum rainfall at Andong Dam ...
