WebOct 14, 2024 · Theil Sen Regression in Python. The problem of computing the median slope can be completed in O(n log(n)) or even faster, where n is the number of points. So this method is very fast as much as it is robust. An estimate gives that even if 30% of the data points are corrupted, Theil Sen Estimator will still gives satisfactory results. WebThe Theil-Sen trend estimation method "is insensitive to outliers; it can be significantly more accurate than simple linear regression for skewed and heteroskedastic data, and competes well against non-robust least squares even for normally distributed data in terms of statistical power.

The Sen slope (alternately, Theil or Theil-Sen slope)—the median slope joining all pairs of observations—is expressed by quantity per unit time. The fraction of missing slopes involving the first and last fifths of the data are provided so that the appropriateness of the slope estimate can be assessed and results flagged.

It returns the median all computed slope value … The median slope of a set of n sample points may be computed exactly by computing all O(n ) lines through pairs of points, and then applying a linear time median finding algorithm. Alternatively, it may be estimated by sampling pairs of points. This problem is equivalent, under projective duality, to the problem of finding the crossing point in an arrangement of lines that has the median x-coordinate among all such crossing points.
