In this paper we consider S-estimators for multivariate regression. We study the robustness of the estimators in terms of their breakdown point and influence function. Our results extend results on ...

In this lecture, the univariate twin model is extended to the bivariate twin model. It is explained how the variance in two traits is decomposed into additive genetic, non-additive genetic, and ...

This section illustrates how to solve some ordinary least-squares problems and generalizations of those problems by formulating them as transformation regression problems. One problem involves finding ...

This article concerns the analysis of multivariate response data with multivariate regressors. Methods for reducing the dimensionality of response variables are developed, with the goal of preserving ...

In a recent study published in Frontiers in Endocrinology, researchers evaluated whether insulin-like peptide 3 (INSL3) could predict hypogonadism and age-associated morbidity in older males. Study: ...
