Scalable Approximation of the Transformation‐Free Linear Simplicial–Simplicial Regression via Constrained Iterative Reweighted Least Squares

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Simplicial–simplicial regression concerns statistical modeling scenarios in which both the predictors and the responses contain vectors constrained to lie on the simplex. Fiksel et al. introduced a transformation‐free linear regression framework for this setting, wherein the regression coefficients are estimated by minimizing the Kullback ...

Modeling Heterogeneity in Health Risk Behaviors With a Dynamic Mixture Model Informed by Textual Occupational Data

Statistics in Medicine, Volume 45, Issue 18-19, August 2026.
ABSTRACT Health risk behaviors, including smoking, poor nutrition, alcohol misuse, and physical inactivity (SNAP), are leading contributors to chronic disease burden and healthcare costs worldwide. Their prevalence is shaped not only by individual demographic characteristics but also by contextual factors such as socioeconomic and occupational ...

Network Meta‐Analysis of Survival Outcomes With Non‐Proportional Hazards Using Flexible M‐Splines

Statistics in Medicine, Volume 45, Issue 18-19, August 2026.
ABSTRACT Network meta‐analysis (NMA) is widely used in healthcare decision‐making, where estimates of the effect of multiple treatments on outcomes are required. For time‐to‐event outcomes such as survival or disease progression the most common approach is to model log hazard ratios; however, this relies on the proportional hazards assumption.

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

Modeling of Air Emissions From Co‐Pyrolysis of Polymeric Wastes: Simplex Lattice Design and Artificial Neural Network Approach

Environmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Co‐pyrolysis of plastics is a simultaneous thermochemical conversion of a mixture of plastics to value‐added products. This study quantified air emissions from co‐pyrolysis of low‐density polyethylene (LDPE), polystyrene (PS), and polyethylene terephthalate (PET) at varying mixture compositions.
