This package includes\ntests for trend detection (Cox-Stuart Trend Test, Mann-Kendall\nTrend Test, (correlated) Hirsch-Slack Test, partial\nMann-Kendall Trend Test, multivariate (multisite) Mann-Kendall\nTrend Test, (Seasonal) Sen's slope, partial Pearson and\nSpearman correlation trend test), change-point detection\n(Lanzante's test procedures, Pettitt's test, Buishand Range\nTest, Buishand U Test, Standard Normal Homogeinity Test),\ndetection of non-randomness (Wallis-Moore Phase Frequency Test,\nBartels rank von Neumann's ratio test, Wald-Wolfowitz Test) and\nthe two sample Robust Rank-Order Distributional Test.",
