+implemented by the MICE algorithm as described in @url{Van Buuren and
+Groothuis-Oudshoorn (2011), http://doi.org/10.18637/jss.v045.i03}.  Each
+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.")
