Semiparametric Trending Panel Data Models with Cross-Sectional Dependence [PDF]

A semiparametric fixed effects model is introduced to describe the nonlinear trending phenomenon in panel data analysis and it allows for the cross-sectional dependence in both the regressors and the residuals.

The risk of basal and squamous cell carcinomas of the skin cancer incidence and external radiation in the updated National Registry for radiation workers cohort in the UK

International Journal of Cancer, Volume 158, Issue 3, Page 574-586, 1 February 2026.
What's new? While ultraviolet radiation from the sun is the main risk factor for non‐melanoma skin cancer (NMSC), additional factors contribute to NMSC development. The present study examined the impact of occupational radiation exposure on NMSC risk among radiation workers in the United Kingdom.

A causal inference framework to compare the effectiveness of life‐sustaining ICU therapies—using the example of cancer patients with sepsis

International Journal of Cancer, Volume 158, Issue 3, Page 707-715, 1 February 2026.
What's new? Rising cancer incidence in the United States is associated with an increased demand on intensive care units (ICUs). Critically ill cancer patients, however, often rely on life‐sustaining therapies, which are linked to greater ICU mortality.

A Statistical Framework for Measuring Reproducibility and Replicability of High‐Throughput Experiments From Multiple Sources

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Replication is essential to reliable and consistent scientific discovery in high‐throughput experiments. Quantifying the replicability of scientific discoveries and identifying sources of irreproducibility have become important tasks for quality control and data integration.

A Tutorial on Optimal Dynamic Treatment Regimes

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT A dynamic treatment regime (DTR) is a sequence of treatment decision rules tailored to an individual's evolving status over time. In precision medicine, much focus has been placed on finding an optimal DTR which, if followed by everyone in the population, would yield the best outcome on average; and extensive investigations have been conducted

Causal Inference With Survey Data: A Robust Framework for Propensity Score Weighting in Probability and Non‐Probability Samples

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Confounding bias and selection bias are two major challenges in causal inference with observational data. While numerous methods have been developed to mitigate confounding bias, they often assume that the data are representative of the study population and ignore the potential selection bias introduced during data collection.

Recanting Twins: Addressing Intermediate Confounding in Mediation Analysis

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT The presence of intermediate confounders, also called recanting witnesses, is a fundamental challenge to the investigation of causal mechanisms in mediation analysis, preventing the identification of natural path‐specific effects. Common alternatives (such as randomizational interventional effects) are problematic because they can take non ...

Treatment Effect Heterogeneity of Farmers Participating in Cooperatives

Journal of Agricultural Economics, Volume 77, Issue 1, Page 94-106, February 2026.
ABSTRACT Despite the many studies providing evidence of the benefits of cooperatives, most small farms and farm households, particularly in transition economies, do not participate in them. This study analyses the effect of cooperative activity on farm performance using a large‐scale farm survey conducted in Armenia. In addition, it addresses the issue
