Robust Inference for Intermittently‐Monitored Step‐Stress Tests Under Weibull Lifetime Distributions

Quality and Reliability Engineering International, Volume 42, Issue 2, Page 837-857, March 2026.
ABSTRACT Many modern products exhibit high reliability under normal operating conditions. Conducting life tests under these conditions may result in very few observed failures, insufficient for accurate inferences. Instead, accelerated life tests (ALTs) must be performed.

A General Simulation‐Based Optimisation Framework for Multipoint Constant‐Stress Accelerated Life Tests

Quality and Reliability Engineering International, Volume 42, Issue 2, Page 598-612, March 2026.
ABSTRACT Accelerated life testing (ALT) is a method of reducing the lifetime of components through exposure to extreme stress. This method of obtaining lifetime information involves the design of a testing experiment, that is, an accelerated test plan.

Dynamic Borrowing With a Bias‐Tolerance Cap in Augmented Randomized Controlled Trials

Statistics in Medicine, Volume 45, Issue 6-7, March 2026.
ABSTRACT Although randomized controlled trials (RCTs) are the gold standard for evaluating the efficacy and safety of treatments, they are challenged by cost, duration, enrollment, or ethical concerns. A possible solution is to incorporate external control data as a hybrid control group, for which various statistical methods are available.

Site-Specific Extreme Wave Analysis for Korean Offshore Wind Farm Sites Using Environmental Contour Methods

Journal of Marine Science and Engineering
Reliable estimation of extreme waves is essential for offshore wind turbine system design; however, site-specific conditions limit the application of one-size-fits-all statistical methods.

Sample Size Recalculation in Adaptive Group Sequential Study Designs for Comparing Restricted Mean Survival Times

Statistics in Medicine, Volume 45, Issue 6-7, March 2026.
ABSTRACT Non‐proportional hazards cases are frequently expected in clinical trials with time‐to‐event endpoints (e.g., cardiology, oncology). The relevance of hazard ratios to quantify the treatment effect is questionable and potentially misleading in this context.

Advances in Modal Regression: From Theoretical Foundations to Practical Implementations

WIREs Computational Statistics, Volume 18, Issue 1, March 2026.
Modal regression. ABSTRACT Modal regression has emerged as a powerful alternative to traditional mean and quantile regression by focusing on estimating the conditional mode rather than the conditional mean or quantiles. This approach offers robustness to outliers and skewed distributions while providing more informative prediction intervals for ...

Beyond Normality: Gain‐Probability Analysis for Symmetric Scale Mixture of Normal Distributions

Australian &New Zealand Journal of Statistics, Volume 68, Issue 1, March 2026.
ABSTRACT Gain‐Probability (G‐P) analysis quantifies the probability that a randomly selected individual from one group scores higher or lower than an individual from another group, by varying magnitudes. While G‐P methods have been developed under normality and various skewed distributions, symmetric heavy‐tailed settings remain largely unexplored ...

Mapping Flood Hazard Across Mainland China Through a Physics‐Based Global Flood Model With Embedded Reservoir Operation Scheme

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT China has complex topography, diverse flood mechanisms, and high population exposure, making it highly vulnerable to flooding, highlighting the need for robust national‐scale hazard assessments to identify flood‐prone regions. However, most existing hazard studies are limited to regional scales or rely on empirical indicator‐based methods that
