Vine copula knockoffs for variable selection in gene expression studies

Canadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.

Nonparametric maximum likelihood estimation of the survival function using current lifetime data

Canadian Journal of Statistics, EarlyView.
Abstract An issue when estimating the failure time survival function is how to set up a prevalent cohort study infrastructure to follow subjects after enrollment. This problem can be circumvented through the well‐known Grenander density estimator using current lifetime observations only.

The Weibull–log Weibull distribution for interoccurrence times of earthquakes [PDF]

Physica A: Statistical Mechanics and its Applications, 2009
By analyzing the Japan Meteorological Agency (JMA) seismic catalog for different tectonic settings, we have found that the probability distributions of time intervals between successive earthquakes --interoccurrence times-- can be described by the superposition of the Weibull distribution and the log-Weibull distribution.

Exposure‐Response Analyses of Datopotamab Deruxtecan (Dato‐DXd), a TROP2‐Directed Antibody‐Drug Conjugate, in Advanced Non‐small Cell Lung Cancer

Clinical Pharmacology &Therapeutics, EarlyView.
Exposure‐response analyses supported a favorable benefit‐risk profile of Dato‐DXd at 6 mg/kg Q3W in patients with advanced nonsquamous NSCLC. Datopotamab deruxtecan (Dato‐DXd) is a trophoblast cell‐surface antigen‐2 (TROP2)‐directed antibody‐drug conjugate (ADC) that has demonstrated clinical activity in patients with NSCLC who have received prior ...

The Additive Weibull-Geometric Distribution: Theory and Applications [PDF]

Journal of Statistical Theory and Applications (JSTA), 2016
In this paper, we introduce a new class of lifetime distributions which is called the additive Weibull geometric (AWG) distribution. This distribution obtained by compounding the additive Weibull and geometric distributions.

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Thermal inactivation of Byssochlamys nivea in pineapple nectar combined with preliminary high pressure treatments [PDF]

, 2010
Byssochlamys nivea is a thermal resistant filamentous fungi and potential micotoxin producer. Recent studies have verified the presence of ascospores of such microorganism in samples of pineapple nectars.

Probabilistic prediction of rate‐dependent rock strength using natural gradient boosting and Gaussian process regression

Deep Underground Science and Engineering, EarlyView.
Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic
