On the Foundational Arguments of Sufficient Dimension Reduction

open access: yesWIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Contemporary Sufficient Dimension Reduction, a versatile method for extracting material information from data, can serve as a preprocessor for classical modeling and inference, or as a standalone theory that leads directly to statistical inference. ABSTRACT Sufficient dimension reduction (SDR) refers to supervised methods of dimension reduction that ...

Text Mining in Bibliometrics and Science Mapping: A Methodological Review

open access: yesWIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Text mining has become a foundational component of contemporary bibliometrics and science mapping, enabling systematic analysis of the semantic structure, thematic evolution, and cognitive organization of scientific fields. Integrating textual evidence with relational indicators enriches knowledge maps and supports more comprehensive, content‐sensitive

Rapid City‐Scale Earthquake Assessment by Combining Numerical Simulation and Sparse Sensing

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This study proposes a framework to assess the seismic risk by integrating city‐scale numerical simulations with sensor data prediction. The study begins with advanced numerical simulations using two primary methods: the integrated earthquake simulator (IES) and the stochastic Green's function method.

Strong‐Gradient Diffusion‐Weighted Imaging of Prostate Cancer Using an Inside‐Out Nonlinear Gradient Coil

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2671-2688, May 2026.
ABSTRACT Purpose To demonstrate improved image quality and lesion conspicuity in prostate diffusion‐weighted imaging (DWI) using an inside‐out nonlinear gradient coil that provides locally strong gradients (200–500 500 mT/m) at typical prostate positions.

Total singular value decomposition. Robust SVD, regression and location-scale

open access: yes, 2007
Singular Value Decomposition (SVD) is the basic body of many statistical algorithms and few users question whether SVD is properly handling its job. SVD aims at evaluating the decomposition that best approximates a data matrix, given some rank restriction.

A Tutorial on Bayesian Multi‐Study Factor Analysis With Applications in Nutrition and Genomics

open access: yesStatistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT High‐dimensional data are crucial in biomedical research. Integrating such data from multiple studies is a critical process that relies on the choice of advanced statistical models, enhancing statistical power, reproducibility, and scientific insight compared to analyzing each study separately.

Epigenetic analyses suggest different pathways during pregnancy for development of type 1 diabetes in children with high versus low‐neutral human leukocyte antigen‐risk

open access: yesJournal of Internal Medicine, Volume 299, Issue 5, Page 570-586, May 2026.
Abstract Background and objective The development of Type 1 diabetes (T1D) is shaped by genetic predisposition and epigenetic regulation. Human leukocyte antigen (HLA) risk alleles are major genetic determinants, but the epigenetic landscape in relation to disease onset remains unclear.

Tensor Changepoint Detection and Eigenbootstrap

open access: yesJournal of Time Series Analysis, Volume 47, Issue 3, Page 557-578, May 2026.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

Pacific Decadal Oscillation Modulates an Interdecadal Trans‐Pacific Dry‐Wet Seesaw in East Asian and North American Semi‐Arid Regions

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Semi‐arid regions are expanding globally through divergent pathways: in East Asia (EA) via drying of semi‐humid lands, while in North America (NA) through wetting of arid areas. This interdecadal dry‐wet reversal across the Pacific has remained mechanistically unclear.
