Neighborhood-level heterogeneity in childhood morbidity through generalized linear mixed models [PDF]
ObjectiveChildhood morbidities are crucial for improving long-term public health outcomes. This study aimed to examine the existence of child-specific and regional variation in childhood morbidity based on the cross-cutting study of the Performance ...

Federated generalized linear mixed models for collaborative genome-wide association studies [PDF]
Summary: Federated association testing is a powerful approach to conduct large-scale association studies where sites share intermediate statistics through a central server. There are, however, several standing challenges.

A reproducible, diagnostic-guided hybrid Laplace workflow for generalized linear mixed models [PDF]
Laplace approximation is widely used for generalized linear mixed models because it is fast and compatible with automatic-differentiation software, yet its accuracy can deteriorate when clusters are weakly informative, outcomes are sparse, or conditional

partR2: partitioning R2 in generalized linear mixed models [PDF]
The coefficient of determination R2 quantifies the amount of variance explained by regression coefficients in a linear model. It can be seen as the fixed-effects complement to the repeatability R (intra-class correlation) for the variance explained by ...

Variational Bayesian Inference in High-Dimensional Linear Mixed Models
In high-dimensional regression models, the Bayesian lasso with the Gaussian spike and slab priors is widely adopted to select variables and estimate unknown parameters. However, it involves large matrix computations in a standard Gibbs sampler.

CytoGLMM: conditional differential analysis for flow and mass cytometry experiments
Background Flow and mass cytometry are important modern immunology tools for measuring expression levels of multiple proteins on single cells. The goal is to better understand the mechanisms of responses on a single cell basis by studying differential ...

Generalized linear mixed models can detect unimodal species-environment relationships [PDF]
Niche theory predicts that species occurrence and abundance show non-linear, unimodal relationships with respect to environmental gradients. Unimodal models, such as the Gaussian (logistic) model, are however more difficult to fit to data than linear ...
