Let a sample of size N be taken, by sampling with replacement, from a population of θ disjoint classes, which have no natural ordering. The number of classes is unknown and each class has the probability of 1/θ of being observed. Let nr be the number of classes which occur exactly r times in the sample. Then where d is the number of distinct classes observed in the sample. The purpose of this paper is to investigate some estimates of θ.
