Testing in Nonparametric Accelerated Life Time Models

open access: yesAustrian Journal of Statistics, 2016
A goodness-of-fit test for testing the acceleration function in a nonparametric life time model is proposed. For this aim the limit distribution of an L2-type test statistic is derived.

Use of Wavelet and Bootstrap Methods in Streamflow Prediction

open access: yesJournal of Mathematics, 2023
Streamflow prediction is vital to control the effects of floods and mitigation. Physical prediction model often provides satisfactory results, but these models require massive computational work and hydrogeomorphological variables to develop a prediction

One‐Year Healthcare Utilization and Costs After Emergency Department Encounters for Uncomplicated Appendicitis: A Statewide Observational Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Objective Non‐operative management with antibiotics has emerged as an alternative to appendectomy for uncomplicated appendicitis. This study compared one‐year healthcare costs and utilization outcomes after operative versus non‐operative management of uncomplicated appendicitis using statewide administrative data.

Crop insurance and irrigation behavior: The conditional role of pumping costs

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Excessive water use for irrigation can accelerate the depletion of water resources, undermining agriculture's resilience to weather‐related shocks. Understanding how farmers make water use decisions is essential for developing effective water management policies.

Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

The nonparametric bootstrap for the current status model

open access: yesElectronic Journal of Statistics, 2017
It has been proved that direct bootstrapping of the nonparametric maximum likelihood estimator (MLE) of the distribution function in the current status model leads to inconsistent confidence intervals. We show that bootstrapping of functionals of the MLE can however be used to produce valid intervals.

Biomechanical strain patterns in Meckel's cartilage underlie mandibular variation in FGFR2 mouse models

open access: yesThe Anatomical Record, EarlyView.
Abstract Sequence variations in fibroblast growth factor receptor 2 (FGFR2) are associated with craniosynostosis syndromes, disrupting craniofacial development, yet early mandibular alterations remain poorly characterized. This study examined Meckel's cartilage (MC) and mandibular morphology in mouse models of Apert (Fgfr2+/P253R) and Crouzon ...

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

open access: yesArthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.
