Abstract:

The problem of estimating the number of unseen species in a wildlife sample has been discussed by many researchers. Here a Bayesian approach is used to find the posterior distribution for the number of unseen species under a multinomial-Dirichlet model. The resulting posterior distribution is used to design a future sampling plan (e.g., what is the smallest sample size in order to obtain representatives of all of the species with probability 0.9?).
