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.

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 ...

Multivariate Generalized Linear Mixed Models for Count Data
Univariate regression models have rich literature for counting data. However, this is not the case for multivariate count data. Therefore, we present the Multivariate Generalized Linear Mixed Models framework that deals with a multivariate set of ...

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.

Variable Selection for Generalized Linear Mixed Models by L1-Penalized Estimation [PDF]
Generalized linear mixed models are a widely used tool for modeling longitudinal data. However, their use is typically restricted to few covariates, because the presence of many predictors yields unstable estimates.

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 ...
