theil sen斜率估算theil sen斜率估算 Theil-Sen estimator, also known as the robust estimator of location and scale, is a non-parametric method used for estimating the slope of a relationship between two variables. Unlike other common estimators, such as ordinary least squares (OLS), the Theil-...
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 ...
The Theil-Sen estimator of the slope parameter in simple linear regression is extended to data with both the response and the covariate subject to censoring. Based on inverting a suitable version of Kendall''s statistic, this estimator requires weak assumptions and is simple to compute, and a ...
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. ...
