Power analysis for a mixed effects logistic regression model
In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich …

Regional Low Cerebral Blood Flow Predicts Leukoaraiosis Development at 18 Months in Patients with TIA and Minor Stroke
… was 62+/-12 years, 78% male and 9% diabetic. A mixed effects logistic regression accounting for “within patient” clustering, showed that as CBF increases by 1mL/100g/min, the odds of having a new WMH decrease by 0.61. Results suggest that regions of white matter that develop WMH at 18 months …

Articulatory timing and sound change: a sociophonetic study of /st/ clusters in Seville Spanish
… were evaluated using chi-square tests, and mixed-effects logistic regression. Findings show that while the canonical sibilant remains dominant, younger and females speakers increasingly favor postaspiration and resyllabification, consistent with Labovian models of sound change led by …

Modeling Mortality of Loblolly Pine Plantations
… mortality models were developed using multilevel logistic regression and survival analysis techniques. Multilevel data structure inherent in permanent sample plots data i.e. measurement occasions nested within trees (e.g., repeated measurements) and trees nested within plots, is often ignored in …
