A new parametrization of the Gnedin-Fisher species sampling model
Annalisa Cerquetti · arXiv (Cornell University) · 2010
We introduce a new parametrization for the two-parameter species sampling model with {\it finite} but {\it random} number of different species recently introduced in Gnedin (2010a). We show the reparametrization yields a representation in terms of generalized Waring mixture of Fisher species sampling models and derive the structural distribution of the model.
