The purpose of the Mann-Kendall (MK) test (Mann 1945, Kendall 1975, Gilbert 1987) is to statistically assess if there is a monotonic upward or downward trend of the variable of interest over time. A monotonic upward (downward) trend means that the variable consistently increases (decreases) ...
R: From the “trend” package: sens.slope(x, conf.level = 0.95) Where: x = numeric vector or a time series object of class “ts”, conf.level = numeric significance level. References Minitab 18 Support: Sen’s Slope. Retrieved June 22, 218 from: https://support.minitab.com/en-us...
The Mann-Kendall (MK) test is frequently used for trend detection in hydrological time series although its power has not been systematically studied under the influence of both missing data and aggregation of data (daily, monthly averages). We used Monte Carlo experiments to examine how the ...
We carry out tests for unbiasedness, sign accuracy, and forecast encompassing, followed by the computation of coefficients for topically oriented trend adjustments and the Theil's U measure. We also control for the forecast horizon finding... F Kunze,M Spiwoks,K Bizer,... - 《Managerial & De...
