摘要: This paper collects facts about the number of occupied boxes in classical balls-in-boxes occupancy scheme with infinitely many positive frequencies: equivalently, species represented sam- ples from populations species. We present moments this random variable, discuss asymptotic relations among them and re- lated variables, draw connections regular variation, which appears various manifestations.
