Imputation methods:对于有缺失值的变量采用了pmm(预测均值匹配法)法来插补。BodyWgt、BrainWgt、Pred、Exp、Danger未进行插补,因为这些变量没有缺失数据; VisitSequence:从左至右展示了插补的变量,这里进行插补的分别是sleep数据集中的第3至第7列变量; PredictorMatrix:预测变量矩阵,行=插补变量,列=为插补提供信息的变...
Rationale, aims, and objectives: Missing data represent a challenge in longitudinal studies. The aim of the study is to compare the performance of the multivariate normal imputation and the fully conditional specification methods, using real data set with missing data partially completed 2 years ...
An extensive investigation via simulation is carried out with the aim of comparing three nonparametric, single imputation methods in the presence of multiple data patterns. The ultimate goal is to provide useful hints for users needing to quickly pick the most effective imputation method among the ...
