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) through time, but … See more The following assumptions underlie the MK test: 1. When no trend is present, the measurements (observations or data) obtained over time are independent and identically … See more Suppose there are missing data in the time series. For example, suppose that data are collected the first day of each month, but the data for March 1st and July 1st have been lost. In that case, VSP computes the MK … See more The MK test tests whether to reject the null hypothesis (H0) and accept the alternative hypothesis (Ha), where H0: No monotonic trend Ha: Monotonic trend is present The initial assumption of the MK test is that the H0 is true and that … See more VSP uses a Monte-Carlo simulation to determine the required number of points in time, n, to take a measurement in order to detect a linear trend for specified small probabilities that the MK test will make decision errors.
