A Nonparametric Model of Frontiers [PDF]

In this paper we propose a nonparametric regression frontier model that assumes no specific parametric family of densities for the unobserved stochastic component that represents efficiency in the model.

Interleukin‐2 Deprived State of Regulatory T cells and Their Recovery by Low‐Dose Interleukin‐2 in Patients With Inflammatory Myopathies

Arthritis &Rheumatology, EarlyView.
Objective Regeneration and expansion of Treg by low‐dose interleukin‐2 (IL‐2) therapy is considered a potential treatment strategy for a wide range of autoimmune diseases. To provide a pathophysiologically‐based rationale for low‐dose IL‐2 therapy, we investigated whether reversible defects in the Treg–IL‐2 axis emerge in inflammatory myopathies ...

ANK1 and EPB41 Variants and the Risk of Steroid‐Induced Osteonecrosis

Arthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Publicly funded private schools and academic achievement: A comparative analysis of PISA data in European countries

British Educational Research Journal, EarlyView.
Abstract This paper analyses differences in academic achievement associated with attendance at publicly funded private schools and public schools across 11 European countries. Using eight waves of PISA data (2000–2022), we apply OLS, IPW and IPWRA estimators to account for observed heterogeneity and mitigate selection bias.

Advances in causal discovery methods for ecological time series

Biological Reviews, EarlyView.
ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.

Does Managerial Ability Improve Environmental Performance and Overall ESG Ratings? The Impact of the European Sustainability Reporting Mandate

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the role of managerial ability in driving environmental performance and overall environmental, social, and governance (ESG) ratings in the context of the European Union sustainability reporting regulations. Using a sample of 7242 firm‐year observations over the period 2015–2023, our results indicate a structural change in ...

Estimation of Nonparametric Conditional Moment Models With Possibly Nonsmooth Generalized Residuals [PDF]

This paper studies nonparametric estimation of conditional moment models in which the generalized residual functions can be nonsmooth in the unknown functions of endogenous variables. This is a nonparametric nonlinear instrumental variables (IV) problem.
