Symmetrically Trimmed Least Squares Estimation for Tobit Models [PDF]

open access: yesEconometrica, 1986
This paper proposes alternatives to maximum likelihood estimation of the censored and truncated regression models (known to economists as ``Tobit'' models). The proposed estimators are based upon symmetric censoring or truncation of the upper tail of the distribution of the dependent variable.

A Monte Carlo Comparison of Regression Estimators When the Error Distribution is Long-Tailed Symmetric [PDF]

open access: yes, 2009
The performances of the ordinary least squares (OLS), modified maximum likelihood (MML), least absolute deviations (LAD), Winsorized least squares (WIN), trimmed least squares (TLS), Theil’s (Theil) and weighted Theil’s (Weighted Theil) estimators are ...

truncSP: An R Package for Estimation of Semi-Parametric Truncated Linear Regression Models

open access: yesJournal of Statistical Software, 2014
Problems with truncated data occur in many areas, complicating estimation and inference. Regarding linear regression models, the ordinary least squares estimator is inconsistent and biased for these types of data and is therefore unsuitable for use ...

Enhanced Dynamic Performance in Hybrid Power System Using a Designed ALTS-PFPNN Controller

open access: yesEnergies, 2022
The large-scale, nonlinear and uncertain factors of hybrid power systems (HPS) have always been difficult problems in dynamic stability control. This research mainly focuses on the dynamic and transient stability performance of large HPS under various ...

RobPer: An R Package to Calculate Periodograms for Light Curves Based on Robust Regression

open access: yesJournal of Statistical Software, 2016
An important task in astroparticle physics is the detection of periodicities in irregularly sampled time series, called light curves. The classic Fourier periodogram cannot deal with irregular sampling and with the measurement accuracies that are ...

Approximate least trimmed sum of squares fitting and applications in image analysis [PDF]

open access: yes, 2013
The least trimmed sum of squares (LTS) regression estimation criterion is a robust statistical method for model fitting in the presence of outliers. Compared with the classical least squares estimator, which uses the entire data set for regression and is

Combining some Biased Estimation Methods with Least Trimmed Squares Regression and its Application

open access: yesRevista Colombiana de Estadística
In the case of multicollinearity and outliers in regression analysis, the researchers are encouraged to deal with two problems simultaneously. Biased methods based on robust estimators are useful for estimating the regression coefficients for such cases.
