A note on generalised information criteria for structured sparse models

International Statistical Review, EarlyView.
Summary We propose a generalised information criteria ( gic) that accounts for sparsity pattern in the model. We obtain both asymptotic and nonasymptotic results for model selection. Moreover, we show that the gic is useful for selecting the regularisation parameter in regularised m$$ m $$ estimation in high‐dimensional scenarios.

Estimating and interpreting psychometric networks in neuropsychology: A tutorial with conceptual extensions

Journal of Neuropsychology, EarlyView.
Abstract Network psychometrics has emerged as a promising framework for modelling the structure of neuropsychological data, offering a complementary perspective to traditional latent variable approaches or single test approaches. In neuropsychology, test performance is rarely interpreted in isolation, but rather as reflecting interacting cognitive ...

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, Volume 45, Issue 8, Page 3403-3426, December 2026.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

Key Drivers of Flood Damage Differ Between Low and High Water Depths

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Understanding which factors have the greatest influence on flood damage helps decision‐makers to target interventions more effectively. This study investigates whether the explanatory variables for residential flood damage differ between low‐ and high‐water depth conditions.

Predicting EU Emissions Allowance Prices Using Macroeconomic Indicators and Hybrid AI Models

Journal of Forecasting, Volume 45, Issue 7, Page 3170-3190, November 2026.
ABSTRACT Predicting carbon allowance prices has grown more crucial in relation to carbon market regulation, financial strategy, and environmental policy development. This study examines a hybrid forecasting system that combines deep learning with ensemble machine learning models to forecast the price fluctuations of EU Emissions Allowance (EUAs) within

Machine Learning Estimation of Gestational Age at Delivery Using Linked Mother–Infant Electronic Health Records Across Two Health Systems

Pharmacoepidemiology and Drug Safety, Volume 35, Issue 11, November 2026.
ABSTRACT Purpose This study aimed to develop and evaluate machine‐learning models for estimating gestational age at delivery using EHR data from two health systems. Methods We trained random forest, gradient boosting, and ensemble models using EHR data from mother–infant dyads at Vanderbilt University Medical Center (VUMC) and independently ...

Interpreting Non‐Linear Compaction Mechanics of Expansive Soils Using Reliability Calibrated Framework

Applied Research, Volume 5, Issue 5, October 2026.
This study introduces a reliability‐calibrated machine learning framework to predict the maximum dry density and optimum moisture content of heterogeneous soils. By integrating 15 algorithms with conformal prediction, the models deliver accurate compaction estimates alongside rigorous, distribution‐free 90% confidence intervals.

Joint count transformation models with covariate‐dependent correlations

Ecology, Volume 107, Issue 10, October 2026.
Abstract Joint species distribution models are essential for understanding how ecological covariates shape species communities. However, most existing approaches are limited by rigid parametric distributions for count data and the inability to model how interspecific associations change with those covariates.

Harnessing Large‐Scale Multi‐Omics Data for Risk Prediction and Deep Phenotyping of Valvular Heart Diseases in the General Population

Advanced Science, Volume 13, Issue 53, 24 September 2026.
Large‐scale UK Biobank analyses identify clinical and proteomic signatures for early prediction of valvular heart disease and its subtypes. Proteins add predictive value for VHD, AVS, and MVR, with outcome‐specific compact panels showing translational potential. Multi‐layer evidence highlights matrix remodeling, protease regulation, immune inflammation,
