data.timss1.RdExample dataset TIMSS 2011
The dataset data.timss1 is a list containing 5 imputed datasets.
The dataset data.timss1.ind contains response indicators of these
5 imputed datasets in data.timss1.
The dataset data.timss2 is a list containing 5 datasets in which
only plausible values are imputed, but student covariates are missing.
The dataset data.timssrep contains replicate weights of students.
The dataset data.timss3 is a TIMSS dataset with some missing
student covariates and all 5 plausible values contained in one file.
The dataset data.timss4 is a list containing nested multiply imputed
datasets, with 5 between-nest and 4 within-nest imputations.
