Nonparametric estimations about species not observed in a random sample. (English) Zbl 1225.62044
Summary: A brief survey of work done on two long-standing and important problems in statistics is given. In a simple random sample (with replacement) of size \(n\) from a population divided into species, if \(N\) distinct species are observed, what is the probability that, on the next trial, a species not observed before is discovered? And what is the total number of species not observed?
Interesting in many applied areas, these problems have been discussed in a great number of papers. We survey some of the related publications as well as a Bayes-like estimator recently devised by the authors, together with results on the estimation of the distribution of the probability of discovering a new species.
