Hierarchically structured data Linear regression model Variance inflation factor; 层次结构数据;线性回归模型;方差膨胀因子;
The three common linear regression models are all inappropriate for the hierarchically structured data, but the standard error of the level 1 combined model can be corrected by variance inflation factor in conditions. 当数据具有层次结构时,三类常见的线性回归模型均不适宜,在一定条件下,可采用方差膨胀因子对水平1合并模型的标准误进行校正。
