该分析基于部分折叠的方法,该方法允许某些组件从模型中部分折叠。得到的部分折叠的Gibbs(PCG)采样器被构造成适合线性混合效应模型,预计会比相应的Gibbs采样器表现出更好的收敛特性。为了构建PCG采样器而不使组件更新复杂化,我们考虑通过在线性混合效应模型中根据组内方差表示组间方差来重新参数化模型组件。 简介 已经开发...

linear regression part, and the random effects are associated with individual experimental units drawn at random from a population. The random effects have prior distributions whereas fixed effects do not. Mixed-effects models can represent the covariance structure related to the grouping of data by ...

Linear Mixed-Effects Models for Non-Gaussian Repeated Measurement DataStatistics - MethodologyWe consider the analysis of continuous repeated measurement outcomes that are collected through time, also known as longitudinal data. A standard framework for analysing data of this kind is a linear Gaussian ...

In linear models, effects become coefficients, representing the proportional contributions of model terms. In nonlinear models, effects often have specific physical interpretations, and appear in more general nonlinear combinations. Fixed effects represent population parameters, assumed to be the same each ...

The complexity of linear mixed-effects (LME) models means that traditional diagnostics are rendered less effective. This is due to a breakdown of asymptotic results, boundary issues, and visible patterns in residual plots that are introduced by the model fitting process. Some of these issues are ...
To fit a linear mixed-effects model with the influenza rates as the responses, combine the nine columns corresponding to the regions into an array. The new dataset array, flu2, must have the response variable FluRate, the nominal variable Region that shows which region each estimate is from,...
