Bias-Reduction in Variational Regularization [PDF]

open access: yesarXiv, 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.

REWEIGHTING DATA IN THE SPIRIT OF TUKEY: USING BAYESIAN POSTERIOR PROBABILITIES AS RASCH RESIDUALS FOR STUDYING MISFIT [PDF]

open access: yes, 2010
A new variant of the iterative "data = fit + residual" data-analytical approach described by Mosteller and Tukey is proposed and implemented in the context of item response theory psychometric models.

Gross Motor Function Measure‐66 Item Sets for use with infants and toddlers at high risk for cerebral palsy: Construct validity and responsiveness

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
GMFM‐66‐IS scores were supported by strong construct validity and moderate responsiveness evidence for use with infants and toddlers at high risk for CP. Plain language summary: https://onlinelibrary.wiley.com/doi/10.1111/dmcn.16289 Abstract Aim To evaluate the construct validity and responsiveness of the Gross Motor Function Measure‐66 Item Set (GMFM ...

Navigational Experience and the Preservation of Spatial Abilities into Old Age Among a Tropical Forager‐Farmer Population

open access: yesTopics in Cognitive Science, Volume 15, Issue 1, Page 187-212, January 2023., 2023
Abstract Navigational performance responds to navigational challenges, and both decline with age in Western populations as older people become less mobile. But mobility does not decline everywhere; Tsimané forager‐farmers in Bolivia remain highly mobile throughout adulthood, traveling frequently by foot and dugout canoe for subsistence and social ...
