Coarsening at Random
Søren Feodor Nielsen · Wiley StatsRef: Statistics Reference Online · 2014
Abstract Statistical analysis is often complicated by the presence of incomplete observations. Unfortunately, incomplete observations are unavoidable in many studies. However, if the incompleteness is ignorable, some simplifications to the statistical analysis occur. The concept of coarsening at random is a formalization of what is meant by ignorability of incomplete data.
