⚠️There's a newer version (1.6) of this package.Take me there.

modifiedmk

The package is useful in implementing Non-parametric Mann-Kendall trend tests.

The package contains the following varians of Trend-Tests

  • Mann-Kendall trend test (MK)

  • Mann-Kendall trend test for Pre-Whitened series (PW-MK)

  • Mann-Kendall trend test for Trend-Free Pre-Whitened series (TFPW-MK)

  • Modified Mann-Kendall trend using Variance Correction Approach by Hamed and Rao (1998)

  • Modified Mann-Kendall trend using Variance Correction Approach by Hamed and Rao (1998) considering significant lags upto lag-3

  • Modified Mann-Kendall trend using Variance Correction Approach suggested by Yue and Wang (2004)

  • Modified Mann-Kendall trend using Variance Correction Approach suggested by Yue and Wang (2004) considering only lag-1 auto correlation coefficient

  • Spearman's Rank Correlation test

  • Trend magnitude is calculated by Sen's slope method
