Applications and algorithms for least trimmed sum of absolute deviations regression

DM Hawkins, D Olive - Computational Statistics & Data Analysis, 1999 - Elsevier
High breakdown estimation (HBE) addresses the problem of getting reliable parameter
estimates in the face of outliers that may be numerous and badly placed. In multiple …

Least trimmed squares for regression models with stable errors

MB Shiekh Albasatneh… - Fluctuation and Noise …, 2023 - ui.adsabs.harvard.edu
Abstract Least Trimmed Squares (LTS) is a robust regression method with respect to
outliers. It is based on performing Ordinary Least Squares (OLS) estimates on sub-datasets …

Least trimmed euclidean deviations for robust leverage in regression estimates

C Chatzinakos, G Zioutas - Simulation Modelling Practice and Theory, 2014 - Elsevier
Usually, in the regression models, the data are contaminated with unusually observations
(outliers). For that reason the last 30 years have developed robust regression estimators …

Computation of least squares trimmed regression--an alternative to least trimmed squares regression

Y Zuo, H Zuo - arXiv preprint arXiv:2312.05077, 2023 - arxiv.org
The least squares of depth trimmed (LST) residuals regression, proposed in Zuo and Zuo

A fast algorithm for robust regression with penalised trimmed squares

L Pitsoulis, G Zioutas - Computational Statistics, 2010 - Springer
The presence of groups containing high leverage outliers makes linear regression a difficult
problem due to the masking effect. The available high breakdown estimators based on Least …

Outlier detection and least trimmed squares approximation using semi-definite programming

TD Nguyen, R Welsch - Computational Statistics & Data Analysis, 2010 - Elsevier
Robust linear regression is one of the most popular problems in the robust statistics
community. It is often conducted via least trimmed squares, which minimizes the sum of the k …

Locally and globally robust Penalized Trimmed Squares regression

A Avramidis, G Zioutas - Simulation Modelling Practice and Theory, 2011 - Elsevier
Multiple outliers are frequently encountered in regression models used in business,

Symmetric and trimmed solutions of simple linear regression

C Cheng - 2006 - search.proquest.com
Least trimmed squares (LTS), as a robust method, is widely used in linear regression
models. However, the ordinary LTS of simple linear regression treats the response and …

[PDF][PDF] Nonlinear Least Trimmed Squares

P Čížek - 2001 - Citeseer
The estimation of regression models is often based on the least squares method, which is
very sensitive to misspecification and data errors. An alternative estimation approach is …
