Convergence analysis of generalized iteratively reweighted least squares algorithms on convex function spaces [PDF]
The computation of robust regression estimates often relies on minimization of a convex functional on a convex set. In this paper we discuss a general technique for a large class of convex functionals to compute the minimizers iteratively which is ...

Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.A high‐speed, multi‐color light‐sheet microscope, named quad‐SPIM, enables rapid three dimensional (3D) imaging of large cleared human brain samples with simultaneous four‐channel acquisition. This custom‐built system achieves subcellular resolution across centimeter‐scale volumes, maintaining high image quality.

Partial Linear Quantile Regression and Bootstrap Confidence Bands [PDF]
In this paper uniform confidence bands are constructed for nonparametric quantile estimates of regression functions. The method is based on the bootstrap, where resampling is done from a suitably estimated empirical density function (edf) for residuals ...

Stabilizing Inference in Dirichlet Regression via Ridge‐Penalized Model
Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.ABSTRACT We propose a penalized Dirichlet regression framework for modeling compositional data, using a softmax link to ensure that the mean vector lies on the simplex and to avoid log‐ratio transformations or zero replacement. The model is formulated in a GLM‐like setting and incorporates an ℓ2$$ {\mathrm{\ell}}_2 $$ (ridge) penalty on the regression ...

Robust Distribution‐Free Tests for the Linear Model
Statistics in Medicine, Volume 45, Issue 3-5, February 2026.ABSTRACT Recently, there has been growing concern about heavy‐tailed and skewed noise in biological data. We introduce RobustPALMRT, a flexible permutation framework for testing the association of a covariate of interest adjusted for control covariates.

Recanting Twins: Addressing Intermediate Confounding in Mediation Analysis
Statistics in Medicine, Volume 45, Issue 3-5, February 2026.ABSTRACT The presence of intermediate confounders, also called recanting witnesses, is a fundamental challenge to the investigation of causal mechanisms in mediation analysis, preventing the identification of natural path‐specific effects. Common alternatives (such as randomizational interventional effects) are problematic because they can take non ...

Pointwise adaptive estimation for quantile regression [PDF]
A nonparametric procedure for quantile regression, or more generally nonparametric M-estimation, is proposed which is completely data-driven and adapts locally to the regularity of the regression function.
