WebErosheva, 2013, p. 16). Partial membership models, like the grade of membership (GoM) model (Erosheva, 2002), were designed to allow individuals to be modeled as partial members of several different classes. In this model, in some measure-ments, persons with partial membership are allowed to behave as individuals in one class.
