Analyze another fileStandard-library analysis: the Mann-Kendall trend test with Sen's slope — the classical nonparametric pair for deciding whether an ordered series has a real monotonic trend or is just noise. Computes the tie-corrected Mann-Kendall statistic with a two-sided p-value, Sen's slope (the median pairwise slope) with its classical confidence interval, the implied total change over the window, and an honest serial-correlation caution when autocorrelation would inflate the test's confidence. Works on any dataset: map a date (or sortable index) column and the numeric value to test.
