Description: Power of non-parametric Mann-Kendall test and Spearman’s
        Rho test is highly influenced by serially correlated data. To
        address this issue, trend tests may be applied on the modified
        versions of the time series data by Block Bootstrapping (BBS),
        Prewhitening (PW) , Trend Free Prewhitening (TFPW), Bias
        Corrected Prewhitening and Variance Correction Approach by
        calculating effective sample size. Mann, H. B.
