     Although there is an abundance of statistical literature describing (complicated) methods that can be used to investigate whether or not one is dealing with ignorable or informative missing data in a longitudinal study (see, for instance, Diggle, 1989; Ridout, 1991; Diggle et al., 1994), it is basically quote easy to investigat this matter.

     Another pertinent distinction in Rubin's missing data classification system is whether the missing data mechanism is ignorable.
