Improved Errors-in-Variables Estimators for Grouped Data [PDF]
Grouping models are widely used in economics but are subject to finite sample bias. I show that the standard errors-in-variables estimator (EVE) is exactly equivalent to the Jackknife Instrumental Variables Estimator (JIVE), and use this relationship to ...

Characteristics of Cerebral Palsy in the Midwestern US
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebral palsy (CP) is the most common lifelong motor disability worldwide. Yet, data is limited on how CP manifests in the US. Our objective was to characterize and determine factors affecting functional outcomes in a large population of young people with CP in the Midwestern US.

Model misspecification and bias for inverse probability weighting and doubly robust estimators
, 2017 In the causal inference literature an estimator belonging to a class of semi-parametric estimators is called robust if it has desirable properties under the assumption that at least one of the working models is correctly specified.

The Diverse Neuromuscular Spectrum of VPS13A Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...
