On some issues related to species sampling problems
Stefano Favaro, Antonio Lijoi, Ramsés H. Mena, Igor Pruenster · 2011
ABSTRACT. Species sampling problems have a long history in ecological and biological studies. Data are recorded from a population which is made of different species and, conditionally on a sample of size n, interest lies in the evaluation of the species variety featured by an additional sample of size m. In this talk we review some recent results obtained by adopting a Bayesian nonparametric approach. In particu-lar, we consider two issues: (i) Measurement of species richness; (ii) Assessment of rare species variety. Natural applications are related to sequencing of genomic libraries such as e.g. Expressed Sequence Tags (EST) and Cap Analysis Gene Expression (CAGE). 1
