TLDR
In this article, the authors give some measures of the dispersion of a set of numbers, and define their estimates as those values of the parameters that minimize the residual dispersion, which is asymptotically equivalent to estimates recently proposed by Jureckova.
Abstract
An appealing approach to the problem of estimating the regression coefficients in a linear model is to find those values of the coefficients which make the residuals as small as possible. We give some measures of the dispersion of a set of numbers, and define our estimates as those values of the parameters which minimize the dispersion of the residuals. We consider dispersion measures which are certain linear combinations of the ordered residuals. We show that the estimates derived from them are asymptotically equivalent to estimates recently proposed by Jureckova. In the case of a single parameter, we show that our estimate is a "weighted median" of the pairwise slopes $(Y_j - Y_i)/(c^j - c^i)$.

Least Median of Squares Regression

TL;DR: In this paper, the median of the squared residuals is used to resist the effect of nearly 50% of contamination in the data in the special case of simple least square regression, which corresponds to finding the narrowest strip covering half of the observations.

Intra-household resource allocation: an inferential approach

TL;DR: In this article, the authors show that unearned income in the hands of a mother has a bigger effect on her family's health than income under the control of a father; for child survival probabilities the effect is almost twenty times bigger.

Consistent Nonparametric Regression

TL;DR: In this article, a sequence of probability weight functions defined in terms of nearest neighbors is constructed and sufficient conditions for consistency are obtained, which are applied to verify the consistency of the estimators of the various quantities discussed above and the consistency in Bayes risk of the approximate Bayes rules.

Robust regression by means of s-estimators

TL;DR: A class of methods for robust regression is developed, based on estimators of scale, that are introduced because of their invulnerability to large fractions of contaminated data and are proposed to be called “S-estimators”.

Like Father, Like Son; Like Mother, Like Daughter: Parental Resources and Child Height.

TL;DR: In this article, the authors examined gender differences in the allocation of household resources to child health and found that mothers allocate more resources to daughters while fathers channelled resources toward sons.
