ON THE OCCURRENCE OF THE RANDOM MISSING DATA MECHANISMS
Abstract
That research presents the missing data mechanisms in their classic
definitions. But in the many situations when we implement the field research the lack of
homogeneous multivariate distributions occur. I call them multivariate multilayer
distributions (MMD). The main question that arises is: Are the available definitions of
missing data mechanisms work well in these situations? It’s necessary to make some
clarifications. I demonstrate the missing data mechanisms problems using simulations of
the MMD and EM-clustering end Logistic regressions.
