Nonparametric Tests for Treatment Effect Leveraging Information on Recurrent and Terminal Events and Physiological Decline

open access: yesStatistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT When evaluating treatment effects in progressive disease clinical trials, analyses of time to recurrent or terminal events largely ignore (or separately analyze) functional measures of disease progression over time. For instance, in pulmonary research settings, treatment may impact recurrent times‐to‐hospitalization, mortality and pulmonary ...

Enterprise-level risk assessment of geographically diversified commercial farms: a copula approach

open access: yes
As agriculture becomes more industrialized, the role of risk measures such as value-at-risk (VaR) will become more utilized. In this case it was applied to geographical diversification and also modifying the traditional VaR estimation by incorporating a ...

Empirical Comparison of Win Ratio and Joint Frailty Models for Recurrent Event Endpoints With Applications in Oncology and Cardiology

open access: yesStatistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT Composite endpoints that combine recurrent non‐fatal events with a terminal event are increasingly used in randomized clinical trials, yet conventional time‐to‐first event analyses may obscure clinically relevant information. We compared two statistical frameworks tailored to such endpoints: the joint frailty model (JFM) and the last‐event ...

Multidimensional Distributional Neural Network Output Demonstrated in Super‐Resolution of Surface Wind Speed

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Accurate quantification of uncertainty in neural network predictions remains a central challenge for scientific applications involving high‐dimensional, correlated data. While existing methods capture either aleatoric or epistemic uncertainty, few offer closed‐form, multidimensional distributions that preserve spatial correlation while ...

Convergence of Archimedean Copulas

open access: yes
Convergence of a sequence of bivariate Archimedean copulas to another Archimedean copula or to the comonotone copula is shown to be equivalent with convergence of the corresponding sequence of Kendall distribution functions.No extra differentiability ...

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, Volume 33, Issue 3, Page 1109-1122, June 2026.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...
