Local Associations in Latent Class Analysis: Using Configural Frequency Analysis for Model Evaluation

open access: yesJournal for Person-Oriented Research, 2016
It is proposed to enrich the arsenal of methods for the evaluation of local independence within latent classes by methods from Configural Frequency Analysis (CFA). CFA provides researchers with two additional options. The first involves identifying those

Bayesian Eye Tracking [PDF]

open access: yesarXiv, 2021
Model-based eye tracking has been a dominant approach for eye gaze tracking because of its ability to generalize to different subjects, without the need of any training data and eye gaze annotations. Model-based eye tracking, however, is susceptible to eye feature detection errors, in particular for eye tracking in the wild.

Effects of pregnancy on neuromyelitis optica spectrum disorder and predictors of related attacks

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1918-1925, December 2022., 2022
Abstract Objective Our study aimed to investigate the influence of pregnancy on the course of neuromyelitis optica spectrum disorders (NMOSD) and to explore the independent predictors of pregnancy‐related attacks. Methods We performed a retrospective study of patients with NMOSD based on the Wingerchuk 2006 or the revised Wingerchuk 2015 criteria ...
