混合效应模型(Mixed-Effects Models) 方差分析和多元回归的这些缺点可以通过使用线性混合效应模型(也被称为multilevel modeling或mixed modeling)来避免。混合效应模型允许研究者在研究感兴趣的条件的同时,也考虑到参与者和项目内部和之间的变化。它还能很好地处理缺失数据和不平衡设计;尽管当一个值缺失时,观察值会被移除...

Linear Mixed effect Models are becoming a common statistical tool for analyzing data with a multilevel structure. I will start by introducing the concept of multilevel modeling where we will see that such models are a compromise between two extreme: comp
