Theil–Sen (median slope) estimator, now a Good Article on Wikipedia: en.wikipedia.org/wiki/Theil%E2

This is a method for fitting a line to a set of data points by finding the median slope of lines through pairs of points. It is robust, meaning that (unlike ordinary least squares) a constant fraction of the data can be arbitrarily corrupted without affecting the goodness of fit.

A Mastodon instance for maths people. The kind of people who make $\pi z^2 \times a$ jokes.
