the Theil–Sen estimator, also known as Sen's slope estimator,slope selection,the single median method, or the Kendall robust line-fit method, is a method for robust linear regression that chooses the median slope among all lines through pairs of two-dimensional sample points. It is named ...

Sens’ slope estimator can be used to discover trends inunivariatetime series. It is fairly resistant tooutliers, with a breakdown point of .29 (Wilcox, 2001, p.208). The method, first outlined by Theil and later expanded upon by Sen (1968), is sometimes called theThiel-Sen estimator. ...
