Nonparametric quantile regression for twice censored data

Bernoulli, 2013
We consider the problem of nonparametric quantile regression for twice censored data. Two new estimates are presented, which are constructed by applying concepts of monotone rearrangements to estimates of the conditional distribution function. The proposed methods avoid the problem of crossing quantile curves.

Endoscopic Total Thyroidectomy via a Single‐Port Subclavian Approach Versus Open Surgery for Papillary Thyroid Carcinoma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Historically, performing contralateral thyroid lobectomy and lymph node dissection via the subclavian approach has been considered challenging. This study evaluated the safety and feasibility of gasless endoscopic total thyroidectomy and central compartment neck dissection via the single‐port subclavian approach (SpSCA) in comparison

Mitigating policy uncertainty: What financial markets reveal about firm‐level lobbying

American Journal of Political Science, EarlyView.
Abstract Elections can lead to substantial policy changes and, thus, are a significant source of risk. Firms can respond to such policy uncertainty by lobbying, but it is hard to quantify whether they do so and, if so, how much lobbying benefits them. We construct a new dataset and leverage investors’ expectations of variability in stock returns in the

Asymptotic standard errors for reliability coefficients in item response theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In a recent review, Liu et al. (Psychological Methods, 2025b) classified reliability coefficients into two types: classical test theory (CTT) reliability and proportional reduction in mean squared error (PRMSE). This article focuses on quantifying the sampling variability of these coefficients under item response theory (IRT) models.

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

How endorser attributes influence conservation communication

Conservation Biology, EarlyView.
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

Integrating Indigenous knowledge and modern statistical approaches to model wildlife density based on animal track counts

Conservation Biology, EarlyView.
Abstract In multiuse areas outside formal protection, sustaining both wildlife and people is critical to wildlife conservation and coexistence efforts. Botswana's Kalahari hosts one of sub‐Saharan Africa’s largest unprotected areas supporting free‐ranging wildlife.

The Distributional Effects of Economic Uncertainty*

International Economic Review, EarlyView.
ABSTRACT We study the distributional implications of uncertainty shocks by developing a model that links macroeconomic aggregates to the US distribution of earnings and consumption. Our findings suggest that the fraction of low‐earning workers decreases initially, while the share of households reporting low consumption increases.
