多水平模型（Multilevel Model，MLM），也被称为分层线性模型（Hierarchical Linear Model，HLM），是一种用于分析具有嵌套结构数据的统计方法。这种模型特别适用于处理数据中的层次性或分组结构，例如学生在班级中、班级在学校中、学校在地区中的分布情况。一、基本概念 1. 层次结构：数据集中存在不同层次的单位。例如...
使用MLM进行参数估计的基础知识 MLE 估计的参数值应该最大化的特定样本的似然值 REML 估计方差参数方面比 MLE 更准确,是一种无偏估计,一般情况下用REML 当固定效应不太确定,考虑到测量方差参数(随机效应)的时候用ML 水平2的集群增加的时候,用ML和REML估计之间区别不大 MLMs的假设前提 水平2的残差在集群之间独立 ...
multilevel modelingMultilevel modeling (MLM) is a statistical method designed to accommodate nested data. The method parses variance in the dependent variable of a model to estimate the unique effects of micro- and macro-level independent variables. Interpersonal communication researchers frequently ...

It highlights the conceptual, methodological, and statistical problems associated with these techniques in dealing with multilevel or nested data and discusses an alternative approach, multilevel modeling (MLM), that can handle such data appropriately. An example focusing on contrast effects in essay ...

Because of the nested structure of our repeated-measurement of passive Qzone use and negative emotions (N = 693) within individuals (N = 99), multilevel modeling (MLM) seemed most appropriate to analyze the data (Raudenbush and Bryk, 2002; Wang et al., 2012). Multilevel data analysis al...
A modeling procedure is introduced that includes categorizing datasets into multiple levels, selecting predictors and model solving. MLM, within the scope of this study, is necessary due to an imbalanced survey design and large between-state variations. Overall, MLM appears to be a suitable platform...
Multilevel models (MLMs) are a central building block of the Bayesian workflow. They enable joint, interpretable modeling of data across hierarchical levels and provide a fully probabilistic quantification of uncertainty. Despite their well-recognized advantages, MLMs pose significant computational ...
