Food insecurity and unemployment among immigrants in the United States
American Journal of Agricultural Economics, EarlyView.Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Autism Research, EarlyView.ABSTRACT Internalizing and externalizing problems are highly prevalent among children and adolescents, with higher rates observed particularly among those with neurodevelopmental disorders. Previous studies have identified deficits in social competence and executive functioning (EF) as predictive factors of internalizing and externalizing problems, and

Fit assessment and selection between competitive models in sem
Statistica, 2007 This paper outlines some issues in fit assessment and in selection between competitive models in Structural Equation Models(SEM). The theory on chi-square statistic and the results of some simulation studies are reviewed and the methodological ...

British Journal of Clinical Pharmacology, EarlyView.Aim A prior non‐randomized study suggests that potassium supplementation may improve survival among furosemide initiators, and a randomized trial suggests that salt substitutes containing potassium might lower stroke risk. We conducted a retrospective cohort study using health‐care data to confirm or refute these associations among new users of ...

Parameter uncertainties for imperfect surrogate models in the low-noise regime
Machine Learning: Science and TechnologyBayesian regression determines model parameters by minimizing the expected loss, an upper bound to the true generalization error. However, this loss ignores model form error, or misspecification, meaning parameter uncertainties are significantly ...

Fear of Model Misspecification and the Robustness Premium [PDF]
SSRN Electronic Journal, 2010 Robust decision making implies welfare costs or robustness premia when the approximating model is the true data generating process. To examine the importance of these premia at the aggregate level we employ a simple two-sector dynamic general equilibrium model with human capital and introduce an additional form of precautionary behavior.

Sequential design augmentation with model misspecification [PDF]
, 2007 In Response Surface Methodology (RSM) one attempts to model some variable of interest, usually as a known function of design variables. Subsequent analysis often indicates a need to move to a new region of interest.

Correcting Model Misspecification via Generative Adversarial Networks [PDF]
, 2023 Machine learning models are often misspecified in the likelihood, which leads to a lack of robustness in the predictions. In this paper, we introduce a framework for correcting likelihood misspecifications in several paradigm agnostic noisy prior models ...
