Mann-Kendall Test

Mann-Kendall non-parametric trend test.

Description

The code performs original two tailed Mann-Kendall test. It tests the null hypothesis of trend absence in the vector V, against the alternative of trend.
The result of the test is returned in H = 1 indicates a rejection of the null hypothesis at the alpha significance level. H = 0 indicates a failure to reject the null hypothesis at the alpha significance level.

• MATLAB release: MATLAB 7.5 (R2007b)

Thank you!

It is working very well and is very convenient to use since it returns the result of the hypothesis test, not just the test statistic. But: the alternative of S = 0 --> Z = 0 is not accounted for if I'm right.

For future updates I would also wish for a default significance level (for convenience). And perhaps a mention in the help text that there should be no autocorrelation in residuals.

Hi, Simone Fatichi,

I am new to Mat lab.Please tell me how to give input data and run your Mann_Kendall.m code using Mat lab.
