Retrospective validation of automatic sleep analysis with grey areas model for human‐in‐the‐loop scoring approach

Journal of Sleep Research, Volume 34, Issue 3, June 2025.
Summary State‐of‐the‐art automatic sleep staging methods have demonstrated comparable reliability and superior time efficiency to manual sleep staging. However, fully automatic black‐box solutions are difficult to adapt into clinical workflow due to the lack of transparency in decision‐making processes.

Temporal and sleep stage‐dependent agreement in manual scoring of respiratory events

Journal of Sleep Research, Volume 34, Issue 3, June 2025.
Summary Obstructive sleep apnea diagnosis is based on the manual scoring of respiratory events. The agreement in the manual scoring of the respiratory events lacks an in‐depth investigation as most of the previous studies reported only the apnea–hypopnea index or overall agreement, and not temporal, second‐by‐second or event subtype agreement.

Asymmetric stable stochastic volatility models: estimation, filtering, and forecasting

Journal of Time Series Analysis, EarlyView.
This article considers a stochastic volatility model featuring an asymmetric stable error distribution and a novel way of accounting for the leverage effect. We adopt simulation‐based methods to address key challenges in parameter estimation, the filtering of time‐varying volatility, and volatility forecasting.

Local Whittle estimation in time‐varying long memory series

Journal of Time Series Analysis, EarlyView.
The memory parameter is usually assumed to be constant in traditional long memory time series. We relax this restriction by considering the memory a time‐varying function that depends on a finite number of parameters. A time‐varying Local Whittle estimator of these parameters, and hence of the memory function, is proposed.

Incidental Vocabulary Acquisition Through Captioned Viewing: A Meta‐Analysis

Language Learning, EarlyView.
Abstract Second language (L2) viewing with captions (i.e., L2 on‐screen text) is now a proliferating as well as promising area of L2 acquisition research. The goal of the present meta‐analysis was to examine (a) the relationship between captioned viewing and incidental vocabulary learning and (b) what variables related to learners, treatment ...
