Extending finite mixtures of [formula omitted] linear mixed-effects models with concomitant covariates

2020 · Computational Statistics & Data Analysis

The issue of model-based clustering of longitudinal data has attracted increasing attention in past two decades. Finite mixtures of Student’s-t linear mixed-effects (FM-tLME) models have been considered for implementing this task especially when data contain …

Grouped multi-trajectory modeling using finite mixtures of multivariate contaminated normal linear mixed model

2026 · Statistical Methods in Medical Research

There has been growing interest across various research domains in the modeling and clustering of multivariate longitudinal trajectories obtained from internally near-homogeneous subgroups. One prominent motivation for such work arises from the Alzheimer's Disease Neuroimaging …
