Web15 jun. 2014 · How should the tau number from a Mann-Kendall test be interpreted? I've read that for trends to be detected by the test they must be monotonic. If I have data … WebThere are specific nonparametric techniques that are commonly used for time series data. The Mann–Kendall trend test is commonly used to determine if a trend exists and can handle seasonal patterns within the data. The slope of the trend is often determined with Sen’s slope, which can also handle seasonality in the data.
