A practical approximation algorithm for the LTS estimator
Computational Statistics & Data Analysis, Volume 99, Issue C, 2016, Pages 148-170.
The linear least trimmed squares (LTS) estimator is a statistical technique for fitting a linear model to a set of points. It was proposed by Rousseeuw as a robust alternative to the classical least squares estimator. Given a set of n points in R d , the objective is to minimize the sum of the smallest 50% squared residuals (or more gener...More
