Exam‐level analysis of lecture capture viewing and student exam performance
FEBS Open Bio, EarlyView.This study asks how lecture capture relates to exam performance in biology courses with three noncumulative exams. Mixed‐effects modeling separated between‐students from within‐student effects on exam %. Students who watched more recordings earned higher grades, but viewing spikes above a student's own mean, consistent with cramming, predicted small ...

Confidence intervals for average success probabilities [PDF]
, 2014 We provide Buehler-optimal one-sided and some valid two-sided confidence intervals for the average success probability of a possibly inhomogeneous fixed length Bernoulli chain, based on the number of observed successes.

The Associations Between Chronic Active Lesions and White Matter Disease: A 7 Tesla Imaging Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background The relationship between paramagnetic rim lesions (PRLs) and surrounding normally appearing white matter (NAWM) disease, potentially contributory to the associations seen between PRLs and clinical impairment, is underexplored. Objectives To assess whether PRLs correlate with a greater degree of NAWM injury in early MS.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Prognostication of disease course and prediction of treatment response in multiple sclerosis is an unmet need. We compared the performance of serum neurofilament light chain Z scores (age‐ and BMI‐adjusted) with absolute concentrations for the prediction of response to disease‐modifying therapy.

On Measuring Large Language Models Performance with Inferential Statistics
InformationMeasuring the reliability of performance evaluations is particularly important when we evaluate non-deterministic models. This is the case of using large language models (LLMs) in classification tasks, where different runs generate different outputs ...

On the Effect of Bias Estimation on Coverage Accuracy in Nonparametric Inference
, 2018 Nonparametric methods play a central role in modern empirical work. While they provide inference procedures that are more robust to parametric misspecification bias, they may be quite sensitive to tuning parameter choices.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To investigate the overall use of prescription medications among individuals with multiple sclerosis compared to the general population, with a focus on treatments beyond disease‐modifying therapies. Methods We conducted a nationwide, registry‐based study in Denmark.

Classical and modified rescaled range analysis: Sampling properties under heavy tails [PDF]
, 2009 Mostly used estimators of Hurst exponent for detection of long-range dependence are biased by presence of short-range dependence in the underlying time series. We present confidence intervals estimates for rescaled range and modified rescaled range.

Optimal Bandwidth Choice for Robust Bias Corrected Inference in Regression Discontinuity Designs
, 2020 Modern empirical work in Regression Discontinuity (RD) designs often employs local polynomial estimation and inference with a mean square error (MSE) optimal bandwidth choice.
