Description

This class inherits from the missing_data.frame-class but is customized for the situation where the sample has a multilevel structure.

Details

The fit_model-methods for the multilevel_missing_data.frame class will, by default, utilize multilevel modeling techniques that shrink the estimated parameters for each group toward their global means.

Objects from the Class
