%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
