Quantiles for Fractions and Other Mixed Data [PDF]
This paper studies the estimation of quantile regression for fractional data, focusing on the case where there are mass-points at zero or/and one. More generally, we propose a simple strategy for the estimation of the conditional quantiles of data from ...

Genetic‐Proteomic Integration Identifies Predictive Plasma Proteins for Multiple Sclerosis
Annals of Neurology, EarlyView.Objective Multiple sclerosis (MS) develops after a prolonged preclinical phase. Identifying circulating biomarkers that capture this early biology can improve risk stratification and guide intervention. We aimed to identify plasma proteins driving MS susceptibility using large‐scale proteogenomic integration and to evaluate their prediagnostic ...

Estimation of a censored regression panel data model using conditional moment restrictions efficiently [PDF]
A new semiparametric estimator for the censored regression panel data model with fixed effects is introduced. It is based upon an estimator proposed by Honore for the case of two time periods combined with ideas of Newey to improve the efficiency.

Annals of Neurology, EarlyView.In multiple sclerosis (MS), anti‐CD20 therapies have been associated with increased infection risk, but whether this risk differs between rituximab and ocrelizumab is not known. Using a nationwide cohort, we studied infection risk and relapse outcomes among 16,872 treatment episodes with rituximab, ocrelizumab, or other disease‐modifying therapies ...

CONSISTENT ESTIMATION OF LONGITUDINAL CENSORED DEMAND SYSTEMS [PDF]
In this paper we derive a joint continuous/censored demand system suitable for the analysis of commodity demand relationships using panel data. Unobserved heterogeneity is controlled for using a correlated random effects specification and a Generalized ...

Annals of Neurology, EarlyView.Objectives Nerve transfer is a promising intervention for restoring hand and upper limb function after cervical spinal cord injury (SCI), but the timeline of neurophysiological recovery in humans remains unclear. This study aimed to define recovery profiles after nerve transfers to restore upper limb function.

A SAMPLE SELECTION APPROACH TO CENSORED DEMAND SYSTEMS [PDF]
A censored demand system estimator is proposed by extending the sample selection model of Heckman. Censoring is governed by a selection mechanism which avoids the restricitve Tobit parameterization.

Arthritis &Rheumatology, EarlyView.Objective Interstitial lung disease (ILD) can occur in association with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV‐ILD) or as an isolated entity with positive ANCA (ANCA‐ILD). However, data on the epidemiology and outcomes of these conditions remain limited.

A Metabolomic Signature Predicts Gout Flare Clinical Outcome Associated With Colchicine Prophylaxis
Arthritis &Rheumatology, EarlyView.Objective This study investigated that serum metabolomics, before urate‐lowering therapy (ULT) initiation, could serve as a biomarker for responsiveness to colchicine prophylaxis in patients with gout commencing treat‐to‐target ULT. Methods We studied a multicenter prospective cohort (n = 409) initiating treat‐to‐target ULT plus colchicine prophylaxis.

A Partially Linear Censored Quantile Regression Model for Unemployment Duration [PDF]
Censored Regression Quantile (CRQ) methods provide a powerful and flexible approach for the analysis of censored survival data when standard linear models are felt to be appropriate.
