Bias-Reduction in Variational Regularization [PDF]
arXiv, 2016 The aim of this paper is to introduce and study a two-step debiasing method for variational regularization. After solving the standard variational problem, the key idea is to add a consecutive debiasing step minimizing the data fidelity on an appropriate set, the so-called model manifold.

Maximum likelihood estimation in the sparse Rasch model [PDF]
arXivThe Rasch model has been widely used to analyse item response data in psychometrics and educational assessments. When the number of individuals and items are large, it may be impractical to provide all possible responses. It is desirable to study sparse item response experiments.

Estimation of Models in a Rasch Family for Polytomous Items and Multiple Latent Variables [PDF]
The Rasch family of models considered in this paper includes models for polytomous items and multiple correlated latent traits, as well as for dichotomous items and a single latent variable. An R package is described that computes estimates of parameters

Random pairing MLE for estimation of item parameters in Rasch model [PDF]
arXivThe Rasch model, a classical model in the item response theory, is widely used in psychometrics to model the relationship between individuals' latent traits and their binary responses on assessments or questionnaires. In this paper, we introduce a new likelihood-based estimator -- random pairing maximum likelihood estimator ($\mathsf{RP\text{-}MLE ...

The German Quarterly, EarlyView.Abstract This essay explores the disturbing presence of anti‐Black language and tropes in Emine Sevgi Özdamar's recent, celebrated novel Ein von Schatten begrenzter Raum. Drawing on Toni Morrison's classic analysis in Playing in the Dark, I argue Özdamar's anti‐Blackness is characterized by a double‐valence: on one hand, Özdamar's anti‐Blackness ...

Individual ability on high-stakes test: Choosing cumulative score or rasch for scoring model
Jurnal Penelitian dan Evaluasi PendidikanIn a test, a method is required to estimate an individual's ability based on their responses. Typically, this is done by summing the correct responses or calculating a cumulative score. An alternative method is the Rasch model.
