variable has its own imputation model.  Built-in imputation models are
provided for continuous data (predictive mean matching, normal), binary
data (logistic regression), unordered categorical data (polytomous logistic
regression) and ordered categorical data (proportional odds).  MICE can also
impute continuous two-level data (normal model, pan, second-level variables).
Passive imputation can be used to maintain consistency between variables.
Various diagnostic plots are available to inspect the quality of the
imputations.")
