Linear mixed-effects models are a class of models widely used for analyzing different types of data: longitudinal, clustered and panel data. Many fields, in which a statistical methodology is required, involve the employment of linear mixed models, such as biology, chemistry, medicine, finance ...
Moreover, most of the current model selection techniques are developed for the linear regression model only, and thus may not be appropriate in other model contexts, such as the linear mixed effects model. This thesis explores theory for a fast alternative method to select models and investigates...
2.model assumption: ①y是continuous且dependency response ②subject之间independent, objects within subjects是dependent的【学校和学校之间independent,但是学校里面的学生和学生是dependent】③random effect和error都follow normal distribution ④random effect(σ^2,对应U)和error(τ^2,对应e)都是constant variance的 3...

linear mixed model random effect analysis 线性混合模型(Linear Mixed Model,LMM)是一种统计模型,用于分析具有嵌套结构或重复测量数据的数据集。它结合了固定效应和随机效应,以便更好地解释和预测数据中的变异。 在LMM中,固定效应是指可以量化的、稳定的效应,通常用于解释数据中的变异。随机效应则是指由于随机因素...

I am unsure how to define the formula that defines the linear mixed effects model. I would like to set the vector of subsamples as the response variable (y), the vector of groups as the fixed effect, and the subject identifie...
(ANOVA), general linear mixed effect models (LME), and generalised estimating equations are widely used in analysing longitudinal data due to their simplicity and interpretability1. Although numerous advanced extensions of these statistical techniques have been proposed, longitudinal data analysis is still...
Further, there exist some challenges in the context of model selection. The issues (which are discussed in full within Pledger (2000)) arise because if the models being compared differ in the number of groups of animals, the parameters at the boundary under the null model mean that ...
