Mann-Kendall Trend Test


New Member
Dear members,
I have annual time series (63 years) and I've performed Mann-Kendall test on my data.
The Lag-1 serial correlation is not significant. So, I've used three package to compare the results, and I've confused!

* ZYP package: If Lag-1 serial correlation is significant, it uses Yuepilon method, TFPW, and then performs MK test. Since, the serial correlation in this case is not significant, and zyp package uses "kendall" package to perform MK test, I thought I have to get the same results for a similar test. Do I miss something?
I've attached an image of the results for each test.
